Dave Schotz has won lots of races in all kinds of cars; mostly winning championships in rear-wheel-drive cars. Caster is whether the bottom of the suspension is forward of the top Some drivers like a more conservative setup, while others like a Bonsai approach to corner entry. that excessive camber is causing reduced acceleration or braking performance; Video: Touring Car Ace Slides 1,000-HP Skyline GT-R Around Goodwood! It is easy to illustrate how camber thrust works on a typical circle track race car. all conditions, potentially resulting in power oversteer in corner exits When the car is in the middle of a corner, and the performance with ABS. Shorter wheelbase cars can turn much easier. will tend to make the car understeer - the rear tires will follow the front In the end, the driver will decide what he or she prefers when behind the wheel. of a street car. For a 911, you must run enough rear toe-in so that under hard braking or cornering (or both), if the wheels move into a zero or slightly toed-out condition, rear stability goes away. results in the tires becoming more vertical in the corners, thus increasing (high steering angle) corner entries. and brake less and therefore are able to effectively utilize more camber Those three little adjustments front and rear are all there is to an alignment. Running a lot of rear camber would also heat up the rear tires more, We will safeguard your e-mail and only send content you request. One of the things he mentioned was how a tire needs the slip angle. front camber fixed will make the car understeer more. Same as with rear toe, this adjustment is added by installing aftermarket Medium power RWD track car: zero front toe, minimally positive a car with front toe in. Low power balanced track car: zero toe, front and rear. “Sometimes, you are limited by what your car can do. Rear Toe: None (straight). Jim agreed with Marcel that alignment setups are sometimes track-dependent. Now, if your goal is to go to the track and crush the competition, then use the information above to go out and set your personal best at your next track day. However, if the same FWD car manages to keep its front tires under throttle (this would be power oversteer). toe rear. As with adjustable camber links, the idea is to replace a fixed length OEM link This way the camber thrust from both tires will help the race car turn left. This is on m/t 26x8.5x15 on a 7" wide wheel. with one that has either an eccentric bolt corner exit and not just in the mid corner phase. camber settings be completely independent. So, unless you like buying tires, be careful with how you use these alignment settings. Marcel DeKerpel (in his baby blue Civic) chases a DNN Motorsports Acura Integra around Buttonwillow Raceway. Here, you can see the mechanic using a Smart Camber tool to measure how much camber the wheel possesses. braking performance metric with less camber it can be difficult to even realize car by reducing rear end grip. Depending on your car, you may not be able to adjust all of the parameters. Aftermarket control arms are frequently offered to allow adjustment of toe the car is using the insides of the tires excessively and the outsides makes sense to run maximum caster possible. Miq and others recommend either about 5.5 or “as much as you can get”. Camber is whether the top points of the wheels are facing inward (negative camber) from the front. around the car's center. may outweigh tire wear due to camber, which is why alignment shops With all of this performance-alignment advice for different types of cars, I will leave you with this caution: All of these baseline setups are absolute tire killers if you drive your car daily on the road. Of course, that first lap when the tires are cold you better hold on! Rear Toe: 1/16-inch toe-in total. He is a multi-national champion racing driver and is also the author of the novel, Cadet Blues. with one that has either an eccentric bolt Without him, over half of the field in Southern California wouldn’t start a single race. C. Rear Alignment The direction, in relation to the chassis, that the rearend is pointed can totally dictate how a car will behave in the turns. Follow this guide to reduce that loading and you will go faster. or camber links. throttle. Using a wheel alignment tool kit, you can achieve professional results in your own garage. front camber, which can be useful as FWD cars often need all of the front or alternatively replace the ball joints themselves with Craig Watkins was the engineer for Flying Lizard Motorsports and helped the team earn a pole position at LeMans. He spends his days at his race shop, East Street Racing (ESR) in Memphis, Tennessee, working on customer race cars and provides setup and track support for Spec Miata racers. Front Caster: 6-degrees positive Marcel explains the differences in Honda Challenge. Rob Krider will race absolutely anything. will want less front camber. Marcel discussed what other drivers like with front-wheel drive, “Some people I set cars up for like a more aggressive setup. have a bit of positive front toe aligned into them. Again, tire wear will probably provide the most clues as to what Cars with double A-arm rear suspensions like Miatas can also adjust the rear Cars with double A-arm front suspensions like Miatas can also adjust the front Allow me to introduce you to Marcel DeKerpel. by intermediate-level drivers run -2 to -3 Rear Camber: 3-degrees negative When it comes to alignment specs on a Porsche, I trust no one else. He has won everything there is to win in Spec Miata, both in the SCCA and NASA. Factory Alignment Specs. Thrust Angle. A car with negative rear toe will want to In this video we discuss the pros and cons of different weight distributions for front wheel drive cars. We will start things off with Front Wheel Drive. You’ve heard about torque steer and “wrong-wheel drive” and might write it off as being for grocery-getters, not real performance cars. Craig spent over a decade engineering Porsches in the American LeMans Series setting the cars up for tracks all over the country and beyond. We decided to talk to some seasoned racers who run different types of cars to find out what their baseline alignment specifications are. The inside wheel is which is turned less than the entire car, thus causing understeer. toe produces more drag than zero toe. Ranger Road: Getting Veterans Into Endurance, Video: Scaring Mom In A Lotus Exige Cup 430 At Cadwell, Video: This 1JZ-Swapped Lexus IS300 Is A Budget Track, Get The PerTronix Wiring Products You Need In Your, IDIDIT Performance’s New Steering Hubs Offer Easy Wheel, QA1 Releases 2.5-Inch I.D. The static setting you set on the setup pad is not what the alignment will be when the car is accelerating, cornering, or braking. The Sweet Science of Front Wheel Drive Racing. We promise not to use your email address for anything but exclusive updates from the Power Automedia Network. This is why rear-wheel-drive cars need static toe-in setup in the alignment. “It is really driver dependent, said Marcel. The same eccentrics adjust camber and toe; Many cars require aftermarket camber plates to adjust front camber. To get another perspective from a rear-wheel-drive car — but with a lot less horsepower — we went to Maita Master Jim Drago, who owns East Street Racing (ESR). A very inexpensive and easy way to get more performance out of a car is by merely adjusting the alignment settings. front control arms with You can see the extreme alignment settings on Jim Drago’s Spec Miata. Photo 6/8 | S2000 rear bumpsteer kit versus stock toe arms. This is a problem that is particularly prevalent in the racing world. tires, and will push the front tires forward in a straight line. or an adjustable rod end. A common, though by no means universal, pattern is to have more rear camber This understeering tendency however is very slight. On the track, tire wear due to toe is generally Video: This 1JZ-Swapped Lexus IS300 Is A Budget Track Beast. Cars driven mostly or exclusively on the track For an all-wheel-drive setup for a track day, Dave uses a bit more conservative setting. The following will produce a (more) oversteering car: Because nonzero toe scrubs speed on the straights, it is usually not desired. You will see the alignment specs vary depending on the drive wheels, especially when it comes to rear toe settings. Video: Scaring Mom In A Lotus Exige Cup 430 At Cadwell Park! to road course driving. Other cars can have the front and rear We have also previously covered how to use pyrometer data to make better-informed alignment decisions. And the drivers don’t like that, which will affect lap times.”. effective way to change the balance of the car. Less experienced drivers who do not corner as hard Understeer rather than oversteer is important so that the car can That said, road course cars try to minimize toe in to reduce drag and and mid-corner understeer/oversteer balance. Say the car already corners on 3 wheels, and has plenty of rear traction. the front tires quicker under braking without ABS or have reduced braking High power drift car: negative toe front, minimally negative to However, it is rare to set up a rear-drive race car toed out in the rear, since doing so causes excessive oversteer, particularly when power is applied. On FWD. control arms or As long as the camber is not excessive in the sense that it begins to reduce initially turns in and when it is in the middle of a corner, the typical under power which will result in the driver lifting to keep the car Marcel owns DK Racing, which builds and maintains most of the Honda Challenge fleet racing in the SoCal Region of NASA. Front Toe: None (straight) the tire contact patch size under all conditions, making the front camber Excessive rear camber will produce a reduced rear contact patch size in For a Spec Miata, which has independent suspension and rear-wheel drive, Jim agrees with Craig and runs toe-in in the rear. There is nothing to change in the back of those cars. Front Caster: 5-degrees positive If you set a static rear toe-out setting on a Porsche 911; under acceleration, the suspension moves, pointing those rear tires outward more than you would prefer, which makes the car extremely scary to drive. More rear toe-out for a loose feel? In cars where caster helps avoid positive camber gain in corners, it the adjustment potential and handling of the car. According to Craig, the fact the car is rear-wheel drive completely changes the rear toe settings from a front-wheel-drive setup. run, especially on the driven wheels. Low to medium power street car: minimally positive toe, front and rear frequently would say that toe is the most important parameter to be correctly I was almost going to pull out of the race on the weekend but now that it's been sorted I'm excited about the race Video: How Does One Build Confidence In A Race Car? With FWD and RWD drive covered, it was time to get an all-wheel-drive perspective. braking, especially when braking in curved paths. “With a powerful rear-engine car like a Porsche, toe angles in the rear are particularly important,” said Craig. under braking (front toe) and acceleration (rear toe in a rear wheel drive car, weight is transfered to the outside tires, front toe has the opposite effect Rear Camber: 4-degrees negative This can be done by adjusting the caster, camber, and toe settings to help align the four tires on your car in a way that helps the car get around corners quickly and down the straights faster. camber and caster adjustments first and only if they are insufficient, Front toe is generally adjustable on all modern cars via tie rods. Rear Toe: 1/8-inch toe-in total. and smallest when the car is cornering. “For a 911, static rear toe-in is very important,” said Craig. We'll send you raw engine tech articles, news, features, and videos every week from TURNology. fortunately, tire wear would generally obviously indicate that aftermarket camber/caster plates None of these wheels are pointed straight, nor are they straight up and down. From turn plates to toe plates, camber/caster gauges to bump steer gauges, Intercomp manufactures a wide variety of analog and digital alignment equipment used by professional teams and grassroots racers all over the world. run the same size tires front and rear. On road courses this is required for stability in high speed corner entries and for Track cars usually are set up with a touch of understeer. With most production cars set up to strongly understeer from the factory, © 2020 Power Automedia. The same eccentrics adjust camber and toe; of the suspension (positive caster) or rearward (negative caster). Obviously wheel alignment, and in particularly toe settings, are going to be wildly different on a FWD grip/race car than it is on a RWD drift car, for example. In FWD and to a lesser extend AWD cars, In this in-depth video, Tim McAmis covers all aspects of front end alignment. A McStrut FWD is pretty much the perfect storm of suck when it comes to tradeoffs between maximum cornering and maximum straight-line acceleration. further into the corner and continuing to rotate the car. FWD track cars may resort to extreme amounts of rear camber to balance the A car with zero toe has the wheels exactly parallel to each other. In cases when other suspension components are changed in For a start, the driver is always turning in the same direction, instead of being able to turn left and right, which has an immediate impact on how you need to align the wheels for the race. Obviously the high amount of camber will come at the expense of tire wear. a small movement of the steering wheel will be sufficient to get the car to rotate. A car with front toe out will initiate direction changes more easily than “If I’m running Hoosier tires then I want 4-degrees of negative camber because that’s what those tires like,” said Dave. A car with positive rear toe will tend to keep Build your own custom newsletter with the content you love from Turnology, directly to your inbox, absolutely FREE! On a road course front toe primarily affects eagerness of the car to turn Camber controls the size of tire contact patch on the respective wheel. For expertise on setting up a front-wheel-drive race car, who better than a Honda Challenge racer and mechanic? via the trailing arm link at the forward end of the trailing arm. Published: June 26, 2013; updated: October 3, 2017. Front Toe: 1.5 millimeters out on both sides (3 millimeters out total) A car with significant front toe out will feel "darty": A car with excessive negative camber exist which help in separating toe from camber adjustment by adding an For example, cars with solid rear axles generally cannot adjust rear camber. eccentric bolts, camber/caster plates, etc. I have discovered and developed the Dynamic Rear Steer(DRS) system for VW race cars that works for all racing situations. Rear Camber: 2.5-degrees negative Caster is normally adjusted the same way front camber would be - via But how you dial in your toe settings is going to depend on your driving style, how the rest of your suspension is setup, and what type of handling balance you’re aiming for. drive car, rear tires continue to be loaded unevenly through much of the braking and turning. and camber on all corners of a car. Cars with double A-arm front suspensions like Miatas can also adjust the front toe The car still pushes really hard in the turns and I have to really try to get the rear end to slide at all. Rear tire pressure on FWD racecars - posted in The Technical Forum Archive: I would like to know if there are established methods of setting optimal tire pressures in the rear tires of FWD racecars. road course setup employs either zero front toe or minimal front toe in FWD track cars may resort to extreme amounts of rear camber to balance the car by reducing rear end grip. We have covered Do-It-Yourself Alignment before on TURNology which gives a great overview of what caster, camber, and toe is for vehicle alignments. The above discussion assumes a car going straight, with equal weight on additional eccentric. Dedicated track cars and race cars piloted by advanced-level drivers Its a 1/4 mile track with a slight bank on the turns. The car is ready for the alignment. Front Camber: 3.75-degrees negative He is a NASA Regional Champion and certainly knows his way around wrenching on front-wheel-drive cars. Other cars with double A-arm front suspensions like Civics can replace Because, when the front tires are toed-out, there is a constant slip angle on the tire and distortion, so when you turn the wheel the car instantly goes that direction. Rear Toe: 1 millimeter on both sides (2 millimeters in total), Front Caster: 7 to 9-degrees positive You will see the alignment specs vary depending on the drive wheels, especially when it comes to rear toe settings. A car with positive front toe will tend to track straight even in the Front Camber: 1.5-degrees negative Camber: What Is It And How Can It Make You Faster, The Pros And Cons Of A Sequential Gearbox, The Appeal of Pushrod Suspension: Why and Why Not. left and right tires. Any positive or negative increase tire life. How To Do FWD Drifting Drifting is a driving technique , or a stunt more appropriately, where the driver deliberately oversteers to make the rear wheels or all tires lose traction but without losing control for the entirety of a corner. but with more nuances. Alignment comes down to setting up how your tires adhere to the road surface. As most cars are limited by grip its rear tires following the front tires; it wil tend to be stable under In talking with Marcel, we learned he had two different concepts for front-wheel-drive road racing setups. On a car with positive toe, or toe in, lines drawn parallel to the wheels converge Schwartz Performance’s “Skart” Rules All, SEMA 2020: Miller Electric Offers New Enthusiast-Friendly Welder. Hence excessive negative camber normally first manifests in uneven tire wear, majority of the time is spent driving in straight lines, the effects of this To cover performance alignment specs for a rear-wheel-drive car, we reached out to Craig Watkins who races Porsche 911s, was the engineer for Flying Lizard Motorsports, and owns Smart Racing Products. Many cars do not have a way of adjusting the rear toe from the factory, via eccentric bolts. By Jack Baruth. Going with narrower rear tires is impractical. Getting it to rotate is a problem. Street Legal Mario Kart! We are going to break these different alignment specifications down into Front-Wheel Drive (FWD), Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD). on how hard the driver corners vs how hard they brake. A FWD car heating up its front tires past their optimal temperature range DNN prefers the more aggressive alignment settings with lots of rear toe-out to help the car rotate. In contrast, virtually all street cars have more rear camber than front, MacPherson strut cars would generally install camber in a corner; the harder the car turns, the greater the camber gain. mid corner and may even cause oversteer under power in front wheel drive cars. camber via eccentric bolts. They prefer 3.25-degrees of negative camber in the front, with 3.75-degrees of negative camber in the rear. “We run pretty much the same setup, a neutral setup for Spec Miata for cross-weights unless we are at Mid-Ohio,” said Jim. resistance to heat buildup, also come into play. rear control arms and more front camber than rear camber Front Camber: 2-degrees negative Usually cars have positive caster, the question is only how much of it. The initial turn in is good but it can't hold the line and pushes wide through the corners. diverge forward of the car. Front Caster: 7-degrees positive At the same time the weight is largely sitting on the outside front tire, High power RWD/AWD track car: zero to minimally positive front toe, additional eccentric. Rear Toe: 1.5 millimeters on both sides (3 millimeters in total). On the street, since the overwhelming Dave’s recommendation for an all-wheel-drive car was similar to that prescribed by Craig Watkins for a rear-wheel-drive Porsche — using static toe-in to keep the rear wheels pointed straight under hard acceleration. toe via eccentric bolts. such a way that the car oversteers (such as installing a huge rear The three major alignment parameters on a car are toe, camber, and caster. the car to exit corners going straight under throttle rather than going into a These specs may help you set up the car before your next track day. drag in terms of tire wear minimally positive toe rear depending on car balance and driving style. (1/32"-1/16" per side). on the driven wheels would tend to spin them under throttle, An extreme amount of toe can produce noticeable drag on the straights aftermarket control arms within their ideal temperature envelope, it can be more aggressive with the He mentioned cars like older generation Mustangs or Camaros with solid rear axles don’t have a toe adjustment. pointing further into the corner than the car overall. Without a baseline acceleration and a less significant consideration than tire wear due to camber. camber via eccentric bolts. The thrust angle is an imaginary line drawn perpendicular to the rear axle's centerline. Front Caster Adjustment. toe links Adding camber will make the rear of the car more planted in the corners. Road Racing -0.5 to -2.0 Deg 2.0 to 7.0 Deg 0 to 3/16-inch IN I am not going to profess that this kit is as precise as modern laser-guided alignment racks. Last time out the car would 1.6 with first gear burnouts and low 1.7 with 2nd gear burnouts. double A-arm cars as in these cars suspension pivot points are control arm At Mid-Ohio, he changes the cross-weight. toward the inside edges of the tires. the inside front wheel is unloaded and its contribution to the behavior of the Caster only applies to the front (steered) axle. To see empirically why this is so, consider toe out. the size of contact patch when it is most needed. either direction. to maintain the handling balance. Today we are going to look at alignment settings specifically as they apply “I like a square car, a car that has the same negative camber both front and rear. High power street car: minimally positive toe in on non-driven wheels, For expertise on setting up a front-wheel-drive race car, who better than a Honda Challenge racer and mechanic? When he mentioned that, it made me realize why, when you put toe-out in the front of a car, it feels more responsive and has better initial turn-in. car is minimal. Seems the wheel alignment place didn't tighten up the bolts fully when they did my alignment, so after tightening the bolts I took the car out it's now finally handling well. drift, or powerslide, and tracking straight is obviously a desired characteristic If this is you, start with the "perfect" calculated camber angle, and then back off some static negative and see what happens to your times. So far I have a added a 1/2" rear swaybar and disconnected the front swaybar. on handling: front toe out produces understeer and a car that resists Front Camber: 2.5-degrees negative In drift cars, adding toe out is an easy way to get the car to oversteer more. For that, we looked to a guy who has won more NASA National Championship than anyone else, Dave Schotz, who has spent some time playing with Nissan GT-Rs. substantially positive rear toe. Instead of toe-out in the rear, he sets them up with toe-in. many track alignment settings are designed to move the cars closer to neutral necessitating the replacement of OEM suspension arms with aftermarket … I am racing a 1G FWD NT at my local clay oval track. While it is highly unlikely that any FWD teams would be able to obtain this ideal distribution (unless the rules required a very heavy minimum weight), that's the direction they should be headed. will compromise all of its performance characteristics - acceleration, © 2017 Power Automedia. But be careful finding the edge as you try a new setup, otherwise, you might find the wall before you find out you don’t like the new setup. Idk where my car sits yet in the full 1/4 but it goes low 7s in the 1/8 and close to 110mph in the 1/8. insufficiently, as the following picture demonstrates: In RWD cars, optimal camber setting for the front axle depends I run 3-degrees of negative camber on all four corners and I run zero toe. As mentioned, many if not most track-only cars have front camber more With just the camber and toe change and a practice event with 35 or so runs to really get a feel for the car I went from 5 seconds back (same at two events) to 1.5 seconds back of a new friend. The FWD race car is limited by the dynamic loading of the outside front tire. more negative while keeping the rear camber fixed will make the car RWD cars. Most of the discussion around caster centers on steering effort. exist which help in separating toe from camber adjustment by adding an With the wheel in the air, you’re already at 100 percent load transfer, so start looking to alignment settings and tire pressures. their unfavorable weight distribution. in higher power RWD cars, and a car that is loose everywhere in lower power the rear tires otherwise, such as due to being required by the rules to Rear toe has similar effects to the front toe except, in a rear wheel run -1 to -1.5 degrees of camber, depending primarily on street/track on the front wheels.

Always consider using your factory alignment settings for any daily driven vehicles. car balance, power level and driving style; toe can easily be the most I'm hoping the PF brains trust can help, I recently put in coilovers for the excel and it now handles like a bucket. than front camber on street cars (to maintain significant understeer) This may call for less front camber than a similar RWD "Spirited driving" street cars or dual duty street/track cars If you want anything more than that, you need to install aftermarket upper control arms.”. braking and acceleration, as well as shifting of this contact patch is drag on the straights. Some cars, for example Miatas, desire a specific front to rear camber difference Many cars do not have a way of adjusting the rear camber from the factory. in corners, making camber negative when the car is standing still On a car with negative toe, or toe out, the lines Front-wheel drive gets a bad rap with car enthusiasts. and could easily go into a drift under trailbraking or with aggressive Allow me to introduce you to Marcel DeKerpel. Due to the multitude of differences in tires, track surfaces, suspension types, and driver styles, there is no “one-size-fits-all” solution for a set of performance alignment specifications. Front Toe: 1/16-inch toe-out total High Travel Springs In, Street Legal Mario Kart! The late ’70s model Camaro was (and still is) an extremely popular racing car simply because its wheelbase is the shortest allowed by many local rules. oversteer more, while making the rear camber more negative while keeping the to adjust camber on the front axle. Camber plates are not applicable to Nothing says "triumph of enthusiasm over physics" like a FWD race car. camber they can get to combat the understeer resulting from Indeed, some cars like rear wheel drive Porsches and BMWs Insufficient rear camber will produce a car that has less rear One other thing is make sure the alignment is where the camber hits close to zero when you launch. Although, I will … If the car has zero camber standing still (or driving in a straight line), Jim Drago has won a lot of Spec Miata races, and is the only person ever to win two SCCA National Championships in Spec Miata. Jack and block the back of the car to compensate for the height of the front wheel alignment turn tables. FWD track car: zero to substantially negative toe front and rear, depending on substantial toe in on driven wheels (1/16"-1/8" per side). Factory spec is about +3.4 to +5.4. and a car with excessive front negative camber would tend to lock up accelerate out of corners; an oversteering car will tend to enter a drift With the car on the alignment rack, jack the nose up to duplicate a normal race “attitude” (an inch or two seems to be about right). on pavement. adjustable ones. “Not only because of the rear weight bias, but remember an important major premise: suspension is not infinitely rigid. The situation is reversed for front toe in, with outside front tire pointing is happening. Camber values over -3 degrees are normally only found on the front axle. Camber in the rear of a car works on the same principles as camber in the front, This is why if you look in the street stock pits at your local bullring, most of the cars are shorter wheelbase models, like vintage Camaros.
