What's happening fellas, I've been looking through and haven't seem to run into anyone running really wide rear wheels. I have a set of 18x10 Matte black rota grid drifts (4 of them) but only want to put these on the rear of my brand new M235i. Anyone know if these will fit?

As with most wheels, they will stick out too far from the fender.

Fronts would stick out 27.7mm (1 1/8") more than stock and rear would stick out 57.4mm (2 1/4") compared to stock.

But that wouldn't be too bad of a problem because BMW wheels tend to tuck up under the fender no? I wouldn't need to get spacers maybe? I plan on running KW V2's with this setup. Would like a stiff ride (so to speak).

Stock wheels do tuck a little, but only about 12mm back and 15mm front, so you'd still be sticking out a lot, noticeably so and if you plan to lower it, I'm guessing it would rub pretty bad.

As an example, here is another member's car with 18x8 ET35 front and 18x9 ET35 on here...

His stick out just a bit, which doesn't look bad, but it's pushing it in my opinion. Your set up would stick out and additional 11.35mm more in the front and 27.7mm more in the rear compared to his car.
