Alignment specs?
I'm dropping off the T/A next door this morning to have them align it again after the suspension changes. Car is lowered 1.5" in front and 2" out back. I found the stock specs but if anyone has better suggestions to optimize the setup without eating my tires up I'd greatly appreciate it.

Hi Joe, if you have the stock upper control arms, put as many shims as you can fit on the rear bolts (this increases the castor to usually around 2-3 degrees) and then shim the front bolts to get around a half degree of negative camber. You may have to reduce the back shims if you have too much negative camber.
The positive castor is good for high speed driving and the negative camber is good for cornering; more than one degree of negative camber will wear the inside of the tires. This is the setup I have on my '75 Formula. |

As he said getting alot of caster and negative camber is hard on factory arms. 1/16" toe in. 0.5-1 negative camber if you hit corners hard and as much positive caster as you can get with shims or the arm hits the steering shaft. No cornering 0.0-0.5 negative camber/.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
