If you are stuck on tracking your car with 8inch front rims and 9inch rears it is doable. It will just be a good lesson in traction management. To be honest you are only losing .5 inches from the stock sizes, will still keep the same tire sizes as stock, and the tires will be better.
Go with the R888, they have a fat shoulder, will be wider than the others, and are 100 treadware R-comps. If you go with those tires you will have better traction than a stock M3 on 18s $ PS2s, which people track on all the time. Even though the car is supercharged, it will still act like a high revving M3, you will just have to manage throttle and inputs.
