The car has a 4 link rear.

I run my rear shocks on the Road Runner, at full stiff on both Extension, and rebound. The more RPM, and harder I hit the tire, the faster it goes.


I second the motion. If we back the launch RPM off to say 3k I can take some compression out of the rear shocks to get better weight transfer on a marginal surface. If you launch ot as god intended, at 4500-6000, it needs all of the shock it can get out back and as said it crushes the rear tires as launch RPM is increased.
