Best Pinion angle to start with? What is the best pinion angle to start off with? Car is 80% track and 20% street. Car is roughly 3200lbs has coilovers on all 4 corners and 275 pro radials.
Really just trying to get an overall starting point for setting my suspension to test with so I can make adjustments from there.
Any suspension guru's out there?

Pinion angle will not need to be adjusted more than once, unless you change ride height or torque arm mounting position. It does nothing for traction.
If you run Poly or rubber bushing lower control arms, you will want -2*
If you run rod ends then you can run -1 or 0*
Also, this measurement should be a comparative angle between the engine/trans and rear end. Your rear end should not physically read -2* or whatever you set it for, but that amount less than the angle of the engine/transmission

The ride height is about 1" lower than stock. My LCA are rod ends so I guess I will try to start with -1 and work from there.
Thanks for the input. What is your ride height set at currently?

You will always only know the best settings for your combination is by testing, what another person has done will not always work for you.

Torque arm length, torque arm height at the front, pinion angle, ride height, and LCA angles will indeed effect traction however each individual combination will need something different. Though if you have anything poly related in your suspension worrying about any settings are less critical because their deflection will always change what they where set at while stationary when under acceleration and the older these bushings get the worse it seems to be.
