Quick update:
I ran 265/35 & 295/30 Hoosier R7s on the car at an open track day last week. I believe this is the Max Rubber you can get on a track prepped M2 with camber, lowered suspension, and the correct wheel specs.
I originally tried 295/35 R7s in the rear, but they were too tall and had to go 295/30s. They don't make 265/30 R7s, but the balance was still good front to rear and there was tons of grip and it was a blast!
For cheaper tires, I think I can fit a 305/30 RE-71R in the back, but I probably won't try that until next year.
Again, this is with 19x9.5 ET33 fronts and 19x10.5 ET45 rears. I did need a 3mm spacer for the R7s to clear the front suspension, no spacer needed for the Trofeo’s.
