Default Pinion angle ?

Can anyone tell me what my pinion angle should be or how I figure out what it should be ? I have a 91 Z28 with a LS1 in it and T56. The car is lowered 2 inches all the way around except the spacers that go above the rear springs are missing, I plan on getting some and putting them in. I also have a Random Tech adjustable torque arm in the car so adjusting the angle should be easy. Any insight on this would be appreciated, Thank You. I am also new to the forum

Jay

Jay, we set the pinion angle at a -2 degrees, meaning the front of the rear is angled down. Bob

Thanks Bob, that is what the guy I got the car from said he thought it was but I just wanted to be sure. Any advice for setting pinion angle for when I take the car to the track and put some slicks on it ? This is all new territory for me. Thanks again.

We run them at -2 at the track as well. It seems to be the best setting all the way around for us. Bob

Thanks again Bob. Stuff like this worries me when it comes to replacing U joints, not that it is hard to do it is just a pain in the *** sometimes. I had a dodge ramcharger with a 4" lift and 33's on it and in the first few months I probably put more miles on wrenches replacing U joints then I did on the truck. That is a bit exaggerated but I replaced a lot of them. Thanks again.
