Ok I went to get my car alligned today because someone said it would fix a problem I have, ya see I just bought two new rear tires about 2 months ago and they are already starting to wear out on the inside. But when I went there today the guy said that Z cars came with camber in them so when you take a hard corner the tire will stand up giving you better traction. Does this nonZer know what he is talking about? Anyone have any suggestions that can help me save my $400 dollar tires? Thanks alot. P.S. its a 1980 280zx.

Re: Factory camber???????

that is partially true and not. its most definetly true on the 300ZX but the Z does have some inherint camber. if you can find a good shop, they will have the book that tells what the camber should be and should be able to use "shims" to line it up. if you need i can check and see what the specifications for the rear camber is for you..

That's what I've heard, MSA sells a camber adjustment kit that I'm seriously considering purchasing, if I remeber correctly it was less than fifty bucks.

Re: Factory camber???????

Camber is not whats killing your tires it's toe out.Take it back to a reputable shop and look in the moog or one of the other speciality catilogs for the rear adjusters.They take the place of the bolt on the inner pivot and allow camber and toe adjustment.Maybe call around first since the tool for install is more than the part.Someone may have done this before and may still have the tool.

The 1980 FSM lists the following specs:
Camber -5' - 1 degree 25'
Toe-in 2-4mm (.08-.16in)
The manual has no procedure for adjusting either one. I've had a lot of the rear suspension apart and see no place where you would put shims or make any kind of adjustment. That's why they sell the camber kits - so you can adjust it.

I would guess that your bushings are bad or that the suspension was damaged in an accident at some point.

My car has somewhat the same problem, but I think that mine may be due to sacked out springs. When I accelerate hard (when the most of the tire wear happens) the back end of the car gets close to bottoming out, and the tires would look like this from the back / \ because of the way that the suspension runs through its travel with no parralell links like the fancy vette setups. Just a thought, I gotta get mine figured out too.
