Ok so Ive decided on the SSR competition wheels for my 95 M3 which is currently on stock wheels. Now I have to decide the wheel sizes. These wheels will be on for daily driving, but I don’t drive this car very much (its had 4-6k miles in the past year and ½) and the roads in my area aren’t bad, so Im not worried about their strength. I also will be using the wheels for auto crossing, and eventually track
So my options are….

18x8.5 all around : best of both worlds, looks and lightweight, but the most expensive and even more expensive when I have to get tires that fit this size. And 18s aren’t usually used when auto-crossing or on track from what Ive seen

17x8.5 front 17x9 rear : if I do this will I be able to rotate tires? Someone has told me its possible if I get the right tire size

17x8.5 all around : id rather not but…

17x9 all around : is it even possible?

Any comments/advice is appreciated

thanks

Go for 17x9. If you are on stock suspension, I believe it should fit. If you are slammed, you will most likely have to roll the fenders.
