C63 BC Forged wheels fit?

Newyorktimes88 · 03-31-2023, 11:48 PM

Hi everyone,

I just got a 2018 M5. Love it. I'm coming from a 2018 C63 AMG with BC Forged wheels. Is it possible to reuse these wheels at all? I think bolt pattern is the same 5x112. Any help appreciated, thanks!

20x9.5 +20 front
20x11 +50 rear

265/30 Michelin PS4S front
285/30 Michelin PS4S rear

Rear wheel would need a roughly 3/4 -1” spacer to push the wheels outboard. Front to rear tire size differential is about double stock, which will push you closer to the threshold where traction control engages — though probably not enough to matter. Tire aspect ratio is smaller so the engine rpm will be higher for any given speed, the ride will be a little stiffer, and the wheels will appear smaller on the wheel wells.

Thanks all. I've decided to sell them and will just buy new custom ones. Appreciate all the help, and agreed the offset is nuts lol...
