Topless, thank you for the guidelines. Ok so .7 is the max negative camber available up front. That's better than nothing. I always thought it was strange that Porsche dialed in some negative camber in the back from the factory, but not the front. What do you guys think about some slight toe out up front? Bad idea?

Not needed from the fact that as the car is under heavy acceleration, the front tires will toe-out normally a smidge, so keeping the toe at 0 is going to be the best for a rear drive car.

Some high level (National SCCA champion) AX drivers will add a little front toe out to make quick transitions. They will tell you that it is only for tight quick 30 sec. AX courses and it does make the car twitchy. My typical courses are longer, faster, and I don't drive at their level. Zero toe is a better choice for me. I don't like "twitchy" at 120+.

Ok, good to know. You guys have been great. I didn't want to go to a shop without some specs to shoot for. One more thing, I just had the tires changed and now the car seems to pull to the left slightly all the time. Before it seemed to track straight. What the heck could that be?

Hey do you guys know what the stock alignment specs are for a Boxster S? I searched all over the net and found nadda. I don't know if the Bentley book has that info, but I'll check it when I get home.

Boxster S
I am getting my tie-rod replaced so I will get a new alignment too on a stock Boxster S.
From what I gathered for a mix of daily driving and DE use, these are the specs I am thinking of using:
Front Camber: -1.5 deg
Front Toe: 0 deg
Rear Camber: -2.0 deg
Rear Toe: .01 deg toe in
Anybody care to comment?
Thanks.
