What is maximum negativ camber can I adjust to at the rear wheels with stock suspension.

mdrums

I know the front is -1 but the rear I believe is -2.

frafoss

mdrums,

thanks!

mdrums

Welcome...it might be as much as -2.5 but I believe it is really only around -2. I have -1.6 on my rears and -1 of my fronts as a agressive street/track set up. The rears are wearing well for the track but the inside is wearing a little for the street. The fronts for both street and track could be -1.5 and would still wear really well. At -1 my fronts are wearing a lot on the outside from all the track days I've done recently.

I have -1.2 front and -1.4 rear now. Rear, no problems with wearing on the inside on street, little on the outside on track. Fronts are wearing ok on street and a lot on the outside on track.

Think -1.5 on both front and rear sounds like a good tip for me.

mdrums

How did you get -1.5 on your front? Lowered on springs or GT3 arms? Stock can't go past -1 from what I have been told.

-1.5 all around and the car would be extremely neutral and I bet will have some over steer but I'd like to try it. They put more negitive camber in the rear to help out with oversteer from what I've ben told.

i am at around -1.8 front and about -2.2 in the rear with only pss9

ECS

I just got to -2.5 in the rears and went to GT3 control arms on the fronts with a bunch of shims. Result in the front was -2.8.

frafoss

I'm thinking of doing what som other people have done, get the GT3 arms. I will install PSS9 which lower the car.

To you who has the GT3 arms, do you have a list of all the parts # you need to make the installation?

frafoss

What experience do you have with this setup? What about wearing?

frafoss

Only PSS9, no GT3 arms???

GT3 arms here, had Farnbacher do it so I don't even know the part numbers. About -2 up front, -1.8 rear as it's still a street car. Tire wear is fine all around (50/50 street vs. track).

ECS

FraFoss - I don't have the part numbers either. I haven't been to the track yet with my new set-up but in spirited driving it appears I am getting much better turn-in. Now it just goes where I want it to. Before it was more of a fight. Regarding wear, my commute to work is quite short so I don't expect/have not seen wear issues. The real problem before I did this was incredible wear on the outside fronts during DEs. 95% of the tire was still fine but the outside wear was requiring rediculous frequency of tire changes.

mdrums

ECS, my biggest problem is the outside wear on my fronts too. I had max camber put in the fronts for a stock set up and that is right at -1. Still my fronts are wearing out really bad on the outside edge.

Nugget

I would also be interested in finding out the scope of the work to upgrade to GT3 control arms. Our last autocross here was a much tighter course than usual and it was pretty miserable in my C2S which plowed and understeered the whole way through. I'm looking to get a much more aggressive alignment before our next run at that location and if I'll want to buy parts to get the sort of adjustability I'll want it would be nice to do that first.
