well its an edelbrock aj ta and the papers that came with it says it set at the factory spec.
the car is lowered so thats why i got an aj one but i dont have any vibration now and i dont want to adjust the pinion angle and start haveing vibration.
a shop is puting it on later and i know most of you say like -1 to-2 degrees
for the pinion angle.
should i leave it at the factory spec or have the guy adjust it?
i had very bad traction problems then i put a set of 555r's on and made a very big differance. dont realy spin that much any more

set it to -2 and leave it. you should be fine.

Adjust it! -2* should be a good start.
The factory torque arm spec is only valid for a car at stock ride height.
