Re: Ok what pinion angle for Torque Arm at track? i would start at 2 degrees negative angle. thats a general starting point..
tire pressure and launch rpm is going to be car and track specific. that is some thing you will have to learn there.

Re: Ok what pinion angle for Torque Arm at track? SpeedDemonZ28,
Using an angle finder place it on the driveshaft (a flat smooth spot) and record the angle.
Next place the angle finder on the flat surface where the torque arm mounts to the rear end (this surface is parallel whith the pinion shaft) and record the angle indicated.
Subtract the pinion angle from the driveshaft angle. The result is true pinion angle.
In order to preload the rearend you need negative true pinion angle.Adjust the torque arm so that the front of the pinion goes down,continue to check each angle until the pinion angle is more degrees down than the driveshaft angle.
For stock or slightly modified cars -2 degrees of TRUE pinion angle is a good setting.
good luck

Ok what pinion angle for Torque Arm at track? I'm looking for better 60' times, what angle should I adjust my torque arm to, also I'm running BFG drag radials, what PSI should I run them at and what RPM should I launch(M6 4.10;s), my best 60' on these tires is 2.09, I know they have more in them. I'm going to the track tomorrow any advice would be appreciated! Thanks. ~Tony
