We tried them at 6.5 in an attempt to help the shake and the 60's fell off to 1.19-1.20. 5-5 1/2 psi produced the best 60' times with the Hoosiers and the curent 4-link/shock/ballast combo. Any idea of what IC combinations work on a dragster? The current setting doesn't appear to have been changed since the chassis was built. The powdercoat on the brackets isn't marked at any other holes.....I can measure is up and figure the IC if it'll help.
