I realized two things after my first track day:
1. It will certainly not be my last
2. You can't run MPSS with no camber and expect the tires to survive
So after reading countless threads and setting up a spreadsheet with all the different tire options, here's what I've come up with.
Stage 1 (Now, before my next track day)
1. Ground Control Camber Plates
2. Apex EC-7 (18x9" front and 18x10" rear)
3. Michelin PSC2 (245/40R18 and 265/35R18)
Stage 2 (Over the winter)
1. Ohlins R/T
I was hoping I could get some feedback on the chosen tire sizes, PSC2's are very limited for 18" rims. My daily tires are Conti ECS 255/275 on the 437M's, so my track tires would be slightly smaller than my dailies. I feel that the stock M2 power doesn't require a wider tire, especially if paired with the grip level of a PSC2.
My question is whether you guys think I should be concerned about the raised ride height in the front due to the higher aspect ratio? Here's what it calculates out compared to stock 19s:
Front: -.5mm
Rear: -12.7mm
Once I have the Ohlins I could adjust but should I be concerned enough to downsize the fronts to a 225/40?
Lastly, are there any reputable 19" track wheels, or should I go down the Nitto NT01 route and scrap my SC2 idea?

Since you want a dedicated set of track tires.. why not go NT01/NT05, or even Bridgestone RE71R, or hell Hankook RS4...
Sizes in 18 should be dime a dozen. 245 width is perfect on a 18x9 wheel. 255 is what I'd run on a 9.5" wheel. 265 is perfect for 10.
You want to minimize sidewall flex, and it's that contact patch that the wheel affords is the grip you want in turns. The tire width is sufficient for stock car.
