First, just a reminder that this is a track car, not a cruiser.

We run just enough static negative pinion angle that the driveline & pinion yoke are in line under hard acceleration ... which is always the goal with performance & race cars. The amount of static negative pinion angle required varies with each torque absorber application, but they are all in the 3°-5° range.
