Rear Alignment
 

I just wore out a set of rear tires on the inner shoulder of the tires (equal both sides). I changed the tires and took the car to the shop. Seems like they are at -2.3, when they should be at more or less -1, and there is no play left to adjust it as the former owner had her lowered. It was explained to me that the eccentric screws were already at the most favorable position. Is there anyone out there that would have an idea if there are any way of addressing this - or do I have to just spend more money on tires over the years or alternatively raise it up again?

I think the camber is the result of the suspension drop. I suspect the car is way too low. If you bring it up a bit you should get your camber back (or freedom to move).

Good luck, please post your findings

I assume the OP is talking about camber when he says "they are at -2.3"

I find that toe will kill tires way faster than camber, so what is the toe set like?

I've only had my 964 for 8 months and do not know what the adjustment provisions are on these cars trailing arm suspension setup, but can toe be adjusted also?

I had a similar issue but it was only on one wheel, cause was that the bushing in the trailing arm was gone.

Lived in Europe at the time and got a second hand trailing arm from Freisinger as this was the most cost effective solution.

Did the shop know about all the adjustments? My 993 is pretty low and I set mine at less than 1 degree. There's one adjustment that's right in your face when you're under the car but another on the top front (of the rear suspension), I had to work pretty hard to get to. And if I remember right I had to jack the car up to move it then lower it back down to check it.

I will check if shop missed the top one, even though I don't think so. Thanks for the different ideas.

my car is quite low.
the max camber that we can reach was about -2.3 degress.
for your car ... i think the guys might have mixed up the eccentric screws and the screws might be at the max neg camber setting!!!
