Hey guys.

I've bought a set of 9J x 19" BMW 641M alloys for my M2C and have attempted to fit the fronts with no success.

My car has the BBK and I recognize the BMW recommended alloy offset is 8.5J F and 9J R.

I was surprised the front in a 9J don't seem to go over the brakes. Would the 8.5J fit?

I know these alloys do fit the M2C with BBK so I'm surmising it's the fact I have 9J all round that the problem.

Thanks in advance.

For m2c you need 641m 19 inch

The 640m are 18 inch and do not fit

Sorry I've edited my post.

I do indeed have the M641 alloys in 19".

The 9J doesn't seem to fit over the front BBK though.

I know BMW recommended the 8.5J for the fronts bit the 9J are a 29 offset the same as the standard 788M.

I think it could be due to the fact I've got 9J for the front as opposed to 8.5J.

That's the only thing I can think of.

That was my thinking regarding the offset.

Yes they are OEM. Bought direct from BMW.

I've enquired with them today so will see what they say back.
