Looking for experience and recommendations in terms of optional tire sizes for street (75%) and high speed DE (25%) using DOT tires (e.g. Michelin SC2).

My car is a 2017 2S with Sport Suspension and Sport Package with RSS GT3 lower control arms and tie rod ends. Using factory Spyder wheels (8.5/11.5 x 20). Alignment is stock in rear with -3.0 camber front and 0 toe.

Car is not a daily driver.

Thanks for your help!

Since you are doing mostly street just use the 245/305 setup with MPSC2's. They are a great compromise and are only a little scary in standing water. On the track they are fabulous. Given the limited tires available in your (and my) cars size the MPSC2 is the best for road/track and durability. You should get 20-25 sessions out of set depending on how hard you push them. Also, I have driven a number of times in rain with no issue but I was careful. If your willing to buy track rims and tires then you could run 19's - Hoosiers in 265/315 should fit on car but you'll need wider rims of course.
