Looking to buy a set of BBS wheels, wanting to know if the following rim size would fit without rubbing on a RWD M-sport F10:

F: 20x9 ET25
R: 20x10.5 ET 35

Tires 245/35 + 285/30

Many thanks for your help with my build!

Front should be ok if you're planning to lower it (may poke a bit at stock height).

Rear will be aggressive for sure. It will depend how much camber you have. For example, I have a 9.5" with ET33 and a 275 tire, and with -1.3 degrees of camber it's nearly flush. If I stepped up to a 285 I would need more camber to avoid rubbing, and a 10.5" wheel would poke.

Rear spec is -1.8 degrees, so a 285 on ET35 will be real close. For a given rear toe setting, every -0.5 degrees camber will give you about 3.5mm of extra clearance, about 1/8".

EDIT: Look for a build thread by remmib. He uses an 11" wheel with ET46 and a 295, and it's aggressive but still looks good. Your proposed 10.5 ET35 will stick out 5mm more and the center of your tire will be 11mm farther out. I personally think it will rub.

343m wheels are a popular upgrade and they're 10" ET34 rears. I believe the only way to use them without rubbing is to stick with a 275 tire.

you should be fine with those. i'm running 21x9.5 30mm and 21x11 38mm rears with no rubbing whatsoever on 255/295's! I'm also RWD

If you google f10 or f11 and bbs ch-r which has that rear fitment, there's lots of pics. So I assume it's work's fine.
