I had my first outing this weekend at the nationals (Pro-Stock 13.5 blinky)
During practice, on used tires, i could almost go the pace of the fastest guys(+0.2-+.3 sec), but with new handout tires, my car had just not enough traction (about 0.6 sec slower).The race was affected by some rain, track dried up, afterwards i was just off the pace (about 0.6 sec slower than leaders). I had .5 shims under rear lower arms and i'm still using AM26. Is AM06S a must have to get the lowest possible roll center, i see it on almost all setup sheets, most often with 0mm under arms. Any other hints? THX
