Took the car into my shop today for an alignment and to check the corner balance.
The car runs -1.4/-1.5 negative camber on all 4 corners from the factory.
Bumped it down to -2.6 camber in the front, which required the addition of shims.
Dialed down to -2.4 camber in the rear, no shims needed (can maybe get -2.6 without shims)
zero toe all around.
We didn't bother with corner balancing this time around since the cross weight was 49.9% from the factory. Nice bonus!
Additionally, since people have been having problems with the radiators still getting punctured with the 2015 mesh, we added some more for insurance:
Good idea. Looks like dyi skill level too. Do they come out easy with the front wheels off ?
On the alignment, can you tell us how much in shims you needed? Also are the shims the same as used for prior gen GT3 LCAs? I have a few spare laying around and hopefully can use them when I get around to alignment.

Same shims in the front as the prior gen and cup cars. The rear use different shims, but I haven't needed them.
We used 4 shims total (2 per side, don't know what thickness shim) to get to -2.6 in the front. You can get to around -2.3 without shims in the front.
Joe: What is the OE rear toe spec? Does RWS add toe electronically or does the new geometry just not need it?
I forgot to ask what the factory toe was set at. He did mention that it was set more towards understeer. I asked for zero toe in the rear since I figured that is what RWS is for. At the recommendation of Sam, set toe at zero in front as well.
After talking with people much more knowledgeable than me (ChrisF, thanks), it appears I goofed when I asked for my rear toe to be set at zero. Thankfully, I was able to bring the car back in to have it re-adjusted to a total of 4mm toe in at the rear. NOW I'm ready for tomorrow.
