Steve,
The Hayes manual gives a spec of 1degree negative for rear camber. And
the
rear toe at 0. Our specs at the shop say 1/2 positive camber and 0 toe.
What I got on my car is about 1/2 degree negative and 0 toe. I would look
at maybe turning one of the control arm brackets around. I think there was
an article in Six Pack mag. on this. Within specs is always a wide margin.
If you get it around 3/4 to a 1/2 degree negative you will be fine. But the
wear you are getting sounds like a toe problem. Toe always wears faster
than camber. Camber will eventually wear a tire but not in a short time
that you have driven your car. Also check the wheel bearings and see if
they have any lost motion in the rear. This can give you a negative camber
reading if there is some movement.
I have had no troubles with the rear tires with the specs I set them at.
And no complaints(I Hope) from fellow members of my club with the settings
on their cars.
If you have any more questions, let me know and I will be glad to help.
Also, If you want me to look back in my Six Pack mags. for the article I
can do that.
