M6 Wheels on 640 GC

[spdrcrgtr]

Will the M6 COUPE (or GC) wheels fit on the 640 GC?

Also, what are the specs of the M6 vs 640 20" MSport wheels?

Thanks!!!

The body style of the regular 6 and the M6 are the same. So no wider arches/wheel wells. This has been confirmed by a member that retrofitted the M6 bumper F&R on his 650i GC. So I assume the wheels should be no problem at all!

Specs are f 9x20 and r 10.5x20
No idea on offset.

Thanks for the info. Anyone else thats tried this?

If you find out that offsets I could tell you. 9 in the front and 10.5 in the rear will fit, it just depends on the offset.

[spdrcrgtr]

For the M6 wheels, they are:

Front wheels: 20x9.5" ET31
Rear wheels: 20x10.5" ET19


Ya, I know the widths will fit, just want them to be flush (or close to flush) with the fender. Right now i have 22x9 F and 22x10.5 R and they fit fine

I would be worried about the rears sticking out too much. Stock wheels are 33 offset in front on 8.5 wide wheel and 44 offset in the rear on 9 wide wheel.

The fronts will be about the same but the rears will be about 1.2 inches further out.

hmm.... isn't the suspension, fenders, and entire rear setup the same on the M6 vs the coupe?

The suspension and brakes are different I think--- not sure about the rear fenders...

but If my wheels (10.5) with a 19 offset would sit outside of your fenders that means you have a slightly less aggressive fender line.

I think it would clear everything. But as Vic55 said, it won't be flush.

If you want them flush there are probably some replicas out there that would work. But I am not sure about the quality.

Hm. Ya, the reason why I want OEM is for quality/etc.
