slicks wear pattern

68camaroSS · 10-18-2009, 06:03 AM

The car has run some S/ST, but for the last couple of year's been in bracket mode, run's 6.0''s in 1/8 mile, leave 3,500-4,000 rpm. Just trying to fine tune a couple of things that I wondered about. Always been a "hump" in the racepak driveshaft trace about 3 tenths out that has puzzled me. I have been told diff. causes, the tire running over itself, or could be tire spin, shocks too tight, etc. just trying to pin it down.
The formula from Indyracer would put air pressure at about 9.85 pounds.

Increase rear shock compression damping. What shocks are you running?
