Alignment settings for M030 suspension

Hi, can anyone advise me on what are the wheel alignment setting for a 2001 Boxster 2.7 Tip with M030 suspension ?

My wheel alignment shop has the setting only for a boxster with standard suspension. Ever since I installed the M030 suspension, I always felt that the custom alignment setting that was done on my car didn't feel right. The car is now not as neutral around corners...

Well it really varies a lot depending on how you intend to drive the car and what you mean by "not as neutral". A daily driver will be different than a track rat setup.

My personal preference on an M030 car is a sport alignment:
Front
Max Castor
-2 deg camber approximately
zero toe

Rear
-2 deg camber
1/16th" total toe in (just a touch)

With this setup the tires should wear pretty well, the car will rotate pretty easily, and it will feel stable at speed and in braking zones.

Good point - the car is used as for normal road/highway use. No track.

What I meant by neutral is that the car on the old suspension (except very shaky due to shaking shock shaft) it used to go around corners so fluidly and follows the corners neutrally.

Now the rear seems reluctant to follow the curve and when pushed to limit seems to want to break away. I've lost the rear 3 times already on winding mountain road although it was a little wet. But the tail is catchable.

Yes, I miss the "rotateable" or pivoting around the center of the car feeling the old suspension gives.

Actually, I was wondering if anyone knows what is the Porsche recommendation for alignment figures for the M030 setup.

Fantastic. Thank you very much for the link.

However, the specs is only for the front axle. Any ideas where the values for the rear axle is ?? I did a search on renntech but came up empty handed ? Which section/forum is it in ?
