3. What kind of alignment specs should it get? Again, this is on the street 99.9% of the time and I don't want to have it eating tires. I'm thinking 0 to 1/16" toe-in and 2 degrees negative camber on the front. Is that tire-safe? I have no idea of where to set the rear. Advice?
Thanks for any help/ideas on this.
1. With a car this old anything is better than the old rubber parts. I noticed a huge difference when installing my Energy Suspension polyurethane bushings. Only thing I suggest is greasing them really good every so often.
2. Shouldn't really cause a rougher ride. Makes the suspension work better though.
3. For the street and autocross 0 toe front and back is good. He could try for 1/16th toe out front and 0 toe in the back depending how loose he wants the car. 0 toe will not wear out the tires as much as toe out will. I ran 1/8 toe out front and rear and -3.0 camber front and -2.5 rear and my tires wore pretty evenly. I drove to and from events on my Azenis. Got about 40 events out of the tires (615s) and I still have about 4mm of tread left.
But also realize I'm a pretty smooth driver (at least that's what people tell me) so I'm not as harsh on my tires as say a novice would be. -2 for his car should be a good starting point. I would say -1.5 to -1.8 in the back should be good too.
