A couple of things here... which tracks will you be running, and how many times/year will you realistically track the car? How long do you plan on keeping the car? What is your experience level? You also have several options from changing pad compounds to switching to iron discs, to potentially changing to ST rotors if you want to keep carbon rotors on the car. Send me a pm or email if you'd like and we can discuss it. We may find you can keep running the PCCBs without worry.
If you are dead set on keeping your carbon discs and are concerned with wear/replacement costs down the road, ST carbon rotors may be the solution for you. They last longer, perform better and cost half as much as PCCB discs. OE equipment on Singer 911, Aston Martin Valkyrie, Koenigsegg's,etc...
I'll pretty much be running at NJMP since it's the closest. Maybe Monticello too. I was looking at the njmp thunderbolt track and the average speed is around 85mph
I'd say I'm still a novice with only 3 track days under my belt and I'm not sure how long I'll keep the car but I should start sticking to what I have.. I've gone through 10 cars in 8 years...

Also adding more tire on the rear while keeping oem size on the front doesn't help with understeer....
sorry, meant -3.2/-2.7. Lol
And oddly enough, don’t know how/why, but this is the first time with this setup and I had far less under steer. The rt660 to me is the first real track tire I can consider just perfect. Always used cup2/race2 before, but never again. I beat my PB at Buttonwillow by over 2 seconds, that’s kinda insane. And for the first time, even tire wear, which I could hardly ever get before
no camber plates? If so, what does your LCA shim stack look like?
I actually don’t recall what the shop did, I would have to confirm, but I would assume some shims were added. No mods to camber plate. At -3.2/-2.7, it’s an ideal setup and I doubt I would ever need more.

Never used the RT660, or consider them. So you like like them more than Cup2s? Would you say they are the same or close to a GY SC3R?

I have never used the SC3R so cant compare. I can only tell you that compared to the Cup2, Race2 and RT660, the 660's are the absolute best. I friend of mine who got GT3 .1 started on the cup2 and as he got faster, moved to the SC3R and absolutely loved them and he is slightly faster than I am. From my 2 years of tracking, i can confirm one simple fact, the RT660 have stronger sidewalls!!!! The Cup2/Race2, I always wore out outer or inner sides, but beating my PB by over 2 seconds and having even tear wear, it tells you something. When I started driving on the street for the first time on the 660's, you can feel, its a firmer tire, meaning stronger sidewalls. And this also comes down to speed, I mean someone doing 2 minutes or slower at Buttonwillow CW13, Cup2/Race2/Rt600 will be just fine, zero issues, but I think the faster you get, the better tire you need and that's why I love the RT660. And thank you, I didn't realize the SC3R comes in 245/305, so gonna try those next, should be just as great and should actually be faster, according to all the faster guys I talk to at the track.
Apex VS-5RS 19"X9&11
Falken RT660 265/35 305/30
AP racing rotors/calipers
Rear toe links front camber plates
After several Porsches and uncountable sets of cup2s I have found the Falkens to be a major step up. Much quicker turn in, I've run them in weather hot, cold and in between and they just stick and the tread wear is far superior to the cups.
