About to purchase some RE-71R tires for track duty. Was considering 255/275-35-19 for the M2C stock wheels (788M) but this post caught my eyes (also found that 285s are a bit cheaper than the 275s ).

My car is on stock suspension now. I expect to install camber plates next year, and will likely end up mounting these RE-71Rs on a dedicated set of EC-7 wheels (9.5/10.5). I do not plan coilovers or HAS anytime soon.

I checked w/ Apex to confirm fitment of 285s in their EC-7 rear, and they responded "A 285/35-19 is 2.05% taller in overall diameter compared to the stock M2C rear 265/35-19 rear tire. With an aggressive tire such as the RE-71R there could potentially be scrubbing issues on the rear fender due to the height of the tire and the more "beefy" shoulders that those particular tires have. It might be something you could potentially run on a stock ride height car, however it isn't something I can guarantee a perfect scrub free fitment with."

I'm hoping to confirm that ZM2 experience was with similar stock configuration. I really want to avoid any rub issues. If there is a small chance of rubbing on compression, I'm fine with my original plan of 275s in the rear.
I run this RE71 setup on the 19" EC7s and am lowered on KW v3s. I did have to raise the height a bit in the rear to get the 285s to work, but on most tracks I haven't had any rubbing.
