What to do at the Race Track

[Morris]

Look at this photo close and you'll see how the control arm ball joint of the upper control arm is leaning or on the back side of the shock body. This is the 5*degrees of caster we are using and in order to get it..... if you look at the chassis side of the control arm, you'll see that the front of the upper control arm has material added to it and the rear part of the upper control arm has material taken out to achieve the castor we wanted.

4. When we started using Radial Race Tires back in 1988, we found out the Radials liked a lot of negative camber, and so we start out setting them at around 3*degrees negative on the front and about the same on the Rear with Independent Rear Suspension. And we'll go by our tire temps to know if we want more Camber or less. We don't go by a Camber gauge, the tire Temps tell us what to do to the individual tire to get it flatter on the ground.

a. So we will make adjustments to the camber on each wheel based on the tire temps, There is many things that will affect this reading, how hard is the car being driven, what kind of track are we on, are there more right hand turns then left hand turns, are we in the turn for a long period of time. When we adjust the camber we will only go maybe one or two turns on the heim rod end, just so we can go back to our starting point if we have to.​
b. As you start seeing the temperature across the tire even out then you know you are getting close to the optimum setting for that tire on that track with that driver.​
