.3 variance from left to right is too much. They can do better. Also, on 911, rear camber should be less than front. To get more camber up front you need GT3 lower control arms. A good balance between track and street is about 2.3-2.5 up front and 1.8-2.0 rear. Ie 0.5 difference. OEM front max out at 2 so ask to balance at 1.8 -1.9 Front and 1.4 rear for street driving. If you just go on freeway and no weekend crazy drives, then go to 1.0 up front and 0.5 in rear with zero toe all the way around for optimal tire wear.
Way too much camber in rear for you. Toe front and rear looks good for a good track and canyon driving.

Depends what he’s trying to achieve with his alignment. Street/ track/ both. I agree his rear camber is a bit much but a good alternative is 2.5 that way when he gets front LCA he can just redo the front alignment.
I had a chance to drive the car a bit more yesterday evening and must say it drove really nice, even on the freeway felt pretty good. Are the above recommendation strictly for optimal tire wear or are there other reasons for those suggestions?
To help you;
street driving and commuting; then camber can be 1.0 front, 0.5 rear and zero toe front, 0.1 toe rear. This is more optimal for tire wear. Can even go to 0.05 toe
weekend car and aggressive canyon carving; camber around 1.2-1.3 front, 0.8 rear, zero toe front and 0.15 toe rear.
track toy and mixed weekend driving; camber around 2.3-2.4 And rear 1.8-1.9, zero toe front and 0.2.
Track duty only and slicks, use pyrometer to determine tire temp and change settings accordingly with you as driver. This take time and several track events
The higher the toe Out number, the faster you wear your tires on the inside . But toe in rear is critical for stability at speed and track type breaking, ie eye popping decelerations and turn in
purpose of camber is to flattened the tire when going around corner, ie car is leaning so a high camber tire will give more traction than a zero camber tire.
During steady state cornering, ie freeway ramps, you need some camber but not much.
the most critical camber is under heavy breaking and turn in . You will then transfer weigh to front and same time try to turn, with good camber the front tires are now more flat and therefore more grip. This is mostly most beneficial on track. Why you want more camber in front than rear.
your set up is not ideal for a Porsche and many other cars.
recommend to decrease rear camber and your Toe per driving duty listed above.
