Front end alignment specs, let me know what you think.

This is on a lowered '95 Z28 w/ 17in ws6 rims, and eibach pro's. The car doesn't favor one side of the road, it tends to pull randomly to one side or the other, and sometimes straight as an arrow. And it also grabs the ruts in the road (like when you approach an intersection).

Here are the before and after specs.
................Front Left:.......................Front Right:
................Actual.....Before............. Actual...Before
Camber.....-0.7.......-.07...................-1.1........-1.1
Caster........4.8........4.8.....................5 .3...........5.3
Toe.............0.05.....-0.13..................0.05.......0.09

The car has some improvement in the wandering , it drives more straight an pulls less.

The guy who did the alignment told me to drive the car and see how I like it. If I want I can come back and make some more adjustments.

Please let me know what you think of these specs. and if I should change anything.

Thank you

ok, I just edited this thing 4 times:irk:! For some reason, it squished all my numbers, even though I put spaces in:rolleyes:.

Hope this is better. I also have more numbers on this print out if anyone needs them.

The caster seems excessive. When my car was lowered with the Pro-Kits, I ran -1.0deg camber, +4.0deg caster and 0.1 toe-in, and it seemed to track pretty much the way it always did.... and no signs of irregular tire wear. There is an increased sensitivity to "bumps", and I think that some people try a "bump steer" kit to correct, or minimize the problem.

I never really like the car "lowered", and eventually returned it to stock ride height.

what springs did you use? I dont want to lower my car much if at all. but I want the faster spring rate.

Sorry to jack the thread.

Yea, I read that in one of your prev. posts. The car getting caught in ruts is something I think I will need to live with cause of the wide tires. It's the wandering I don't like. It seems to vere to whatever side of the road I am on, although sometimes I barely have to touch the wheel and it's straight as can be.

I also read about someone adjusting the preload on the rack & pinion unit?

The tendancy to "wander" over the ruts is typical of the ultra wide tires. I found that it seemed to get worse if the tire pressures dropped. I also think I would have checked the "bump steer" kits to see if they helped the "wander". NJ has the worst roads in the country... deep ruts in asphalt from 18-wheelers on all the major roads..... there were times when the car was lowered that I'd get the wheels in both sides in the ruts and the center of the car would rub on the "hump" between them.

I had the Eibach Pro-Kit's, with QA1/HAL shocks. The front dropped more than it was supposed to and the rear dropped less, but the front was correctible with the shock height adjustment. I just felt the rear end had too "choppy" a ride... sort of like what you see on a slammed S10 pickup when its "bobbing" down the road. I played with the adjustment on the shocks, and to get the "chop" out, I had to soften the shocks up too much.

It wasn't a matter of being "harsh"... if it handles well, I'll live with "harsh", but I just didn't like the buckboard style chop of the particular spring - shock combo. I put the Eibach Drag Launch springs in the rear because its more of a "track" car than a street car, and "handling" has gone out the window, with no front sway bar, grossly over-sized "drag-style" rear swaybar, 26x4.5 skinnies, etc.

check out the rag joint in the steering colum. Most of these 93-97 cars have excessive play since the rag joint wears out. If it is that then you will not be able to align the car. these guys http://www.unbalancedengineering.com/Camaro/ sell a metal insert that will elim all play in the steering colum. do a search for rag joint and you will see more info about.
