What do you guys set your pinion angle at with the spohn torque arms? I don't know how to begin setting my pinion angle. Thanks.

 

You take a reading with the anglefinder on the bottom of the flat part that mounts to the rear end - that's supposed to be parallel with the yoke - then you put the anglefinder on the bottom of the driveshaft and take another reading. The diff of the 2 readings is the pinion angle. Just make sure the rear end is pointing down compared to the driveshaft so you have a negative angle. Also, if you get confused under there just hold the anglefinder next to the rear end and point it down a bit to see which way it moves in comparison to the driveshaft - that way you will know you are moving it the right direction. Don't forget to set it back when you leave the track.

And I usually set it at -3° or -4° at the track and 0° for the street. If I raced on the street, I might set it to -2°

 

I have a stick and set mine to -4. That is the max negative pinion angle. Ballpark for automatic car's is -2. Negative pinion angle is hard on the u-joints.
