Thanks a lot for the detailed reply, Ill make sure to bump those threads once I start modifying my alignment beyond what can be done stock. Just curious other sources online mention that rear camber should be slightly less than front, curious why you went with -2.7 front and rear?

Camber on GT4/Cayman/911 and similar (weight placement considerations I guess) is best if square all the way around (where you want to start at the very least). It balances the weight of the mid and rear motors well. Toe is important too. For the GT4, front at slight toe out (negative) or zero toe. Rear w/some (slight) toe in (positive).

Andy Pilgrim (who has assisted me greatly in setting up the car) said to keep camber symmetrical - no need for asymmetry in the set up. As he counseled, "you pretty much always end up with an understeering Cayman GT4 as you have so much weight at the back (same with our Cayman GT4 race cars) but squaring it off will help keep the back stable to start with and you can adjust from there."

And square applies no matter even if you cannot get a higher neg camber due to OEM suspension limitations. The increased camber can come later when you upgrade parts. Same for experimenting with diff (asymmetrical) front and rear camber settings. However, I like mine just as it is - the car does what I want it to do.
