60psi????? I would never go that high on any tire. In road racing you build more heat thus you dont start with pressures like that. The goal of my hoosiers is 40PSI when I come off, usually im very close to that starting with 30-32psi front, 34-36 rear. That is all depending on the ambient temp and track temp.

As for springs, I run 7" now because thats what shine sells with their kit that I bought off someone. The old spring setup was for the original ground control on the car and they where 8" springs.
