987 S Autocross Alignment
Hello- Don't be scared - I have escaped from another forum to ask for some help.
I may wind up at an autocross with my wife's bone stock 987 S and would like to put some negative camber in the front to keep from shredding the outside edges. It has the 19s with Pilot Sports. It is primarily a car to tour with so I do not want to get too radical. Anyone out there with a suggestion/comment on some alignment specs thay have been pleased with ???
Thanks in advance -
BTW -I do really like the car and may break down and get a set of 18s with some "R" compound tires later on.

In stock form, just put max neg. camber in front, which should be about -0.95 deg. I don't think you would want to go with negative toe, but it would help, although I ran well with +0.05 front toe. In the rear, for autox and with 265/40/18 tires, I used to run -1.8 camber and +0.05 toe; not ideal but worked fine for PCA autoxes.
The tire shoulders will be fine unless it is overdriven completely. Also, I used 6 psi difference between front/rear to have a livelier backend and that work well for me as well; although I don't like much oversteer, this was mild and controllable.
You will find differing view and options here for the boxster: http://boxcar-racing.com/forum/index.php?board=1.0

I agree with most of what FlyingToaster said. With the fronts I use 0 toe and got -0.9L -1.1R camber. In the rear you might try a little less camber (minimum I could get was -1.4) I also run 0 toe in the rear but am thinking about going 1/8" toe out (I have a big front sway and the car is focused on autocross)
