Thanks for the great advice... I'm definitely at least a degree off where I think I want to be right now. My current alignment is -1.4 front and -1.8 rear with 0 toe front and .1 toe rear. (The "max" camber is supposed to be -1.3 on the 981 PASM suspension, but Performance Auto was able to get a touch more out of it.)
Bill, that's a handy form! Though I'm curious... how do you measure the track temperature?

That set up is a bit unusual. Normally you run wider tires in rear than in the front. To aid front grip on turn in and because the wider rear tires require less negative camber the front generally carries more negative camber. You likely need upper control plates or GT3 lower control arms to add more camber. Most of us go with the GT3 LCAs when we do it. My Cayman racing set up is more extreme but to give you a sense: 245 fronts/ 305 rears, front -3.9 / rear -3.4
