Bias Ply vs Radial

Tony Curcio · 03-23-2010, 06:03 PM

My experience with an older G-body was that the radials were more consistent with a softer hit. Occasionally, a harder hit would result in better ET's, but only on a well prepped track on a cool day.

One quick way to find out if lowering your instant center (AKA reducing anti-squat) will help is to tighten the shocks on extension. If you get to full tight and the 60 foot times are still improving, you've got to move the IC down. On a G-Body stocker, your only options are to raise the housing-end of the upper control arm mounting points, or buy a complete kit from Alf Weibe. I learned this from Dave Morgan's book by the way- tried it and it worked.

Definitely go with the 10" wheel on a 9' tire. Last- my combo picked up .17 to .18 going from bias to radial .
