Back to the original problem

Now that the axle parts have been replaced, I can focus on the start of this problem.  A wheel base modification was done to try to correct the car from hunting on heavy braking at Road America.  However several other changes also happen at the same time, I believe the wheelbase had no connection with the problem at Road America.  So it's back to my original chassis settings to cleanup this problem of the axle hitting the suspension, once and for all.

I removed the spring and lowered the car to simulate race conditions.
