lal Naja Arthur As far as alignment numbers with a jag rearend with 335 tires, running -.75 camber both sides and 1/16 toed in on both sides. This is with a 1/2 tank of car in the car and your body weight in the drivers seat. I used to run -.50 on camber both sides with 295 tires in 15" rims. You can run more but getting the WHOLE tire on the road is more important along with tire pressures. Auto cross and roadracing you end up with higher tire pressures after a 20 minute run. 8-10psi higher is about the norm. I have gone to nitrogen filled tires and cut the tire pressure increase in half.
I am running poly bushings in my rearend and have almost no deflection of the bushings. They are greased before going to the track. Some Jag rearends are running needle bearings in the carrier arms to the hubs. Again as along as they are grease to remove any play they work ok. I like the polys better.
IMO the most important spec is THRUST angle of the car. You want this a "0" if possible with you in the car. With all things being equal from side to side weights on the car, tire pressures,clean tires, same size curcomfrence, the car should go in a straight line forward every time. No side dances unless you are not straight from the start.
Art I would get CRAZY with how straight the body is on the frame, you can move it around later. Having the suspension right ( wieghting corners ) setup of a 49/51 bias of the car and alignment. will make your car a great handlier.
Some great people have said it's the little things that make a car handle better. I agree with this. Good Luck Rick L.
