If it's across the fronts, wouldn't that be dependant upon which directon the car was turning?

He's saying if the camber was the same value side to side that the car would pull hard to the right......sooooo.......he's saying your beautifully engineered high performance sports car, when the wheels are set to the same alignment side to side.........has been designed to pull to the right?!? Did he mention any frame damage/broken components/anything like that?
If the tires are set the same left to right, the car should track straight (on a flat road) unless something nasty is going on.
That guy is full of crap. I'd find another service advisor to talk to. This guy seems to want you to go away and not actually deal with a potential problem with your car.
Good luck!

I drove the car again alot today and it drives nice on the street. My DE is not until May 12th. It does bug me a whole lot that there is .46 degree camber difference between the RF and LF. That is why I posted my alignment specs because even though I do not know a lot about alignment it just did not seem correct.
So I guess I will call the dealer and again explain my concern and HOPEFULLY will not get into a pissin' match with them because I really like to deal with the sales end of this dealership. ARRRGH why why why me!

Well I have been traveling a lot lately and have taken my alignment specs to various Porsche dealers to get there advice. Suprisingly they all have been very helpful. So far they all said my camber up front between RF and LF should be a lot closer. They also siad that camber does affect to pull of the car to one side or another but they also said that there should not be a .50 degree of difference between RF and LF camber. So I called my dealer and they are being very cool about it and said they will align the car to my specs. I have an appointment this Monday to get this done. They also said they will not be responsable for the way the car drives after this alignment either and they strongly suggested I leave the alingment as is. ARRRGH what freakin frustration!
Should I go for -1 LF and RF or -.5 RF LF? I have -1.5 for the rears. A couple of performance orientated Porsche dealers suggested around -.8 tono more than -1 for the front and no more than -1.5 for the rears as a good street/DE alignment.

Up front I would get as much neg as possible, probably around -1 to -1.2 or so. I would leave the rears alone, thy're already max'd out at 1.5. Ask them to corner balance the car to your weight.

have the front at -1deg leave the rear at -1.5deg. fwiw the rears can go to -2.5 to -2.7 easy.
don't listen to the dealer he told you a lot of bs in the first place. the car will drive well.

I talked to my dealer and they said they could max out the negative camber "with in the specs for a 997S" to help on tire wear at the outside edge. I have read on this forum something about negative 1.5 degrees for front camber and negative 1.8 degrees for rear camber.
Has anyone done this to there 997S before and what where your alignment specs?
Thanks!!!!!! Mike

-2.7 Rear
Alignment performed yesterday on my car which is stock with the exception of H&R lowering springs.
The front adjustment holes were elongated to allow for more adjustment.
