Which (if any) of the UK 6 series 18 inch wheels fit the M6? I'm looking at winter wheel options and would prefer to go the 18" route rather than buy 19" winter tyres for my regular M6 wheels.
The recommended BMW wheels are here In the E60/E61 buyer's guide thread there's someone selling a set.
The offset is different than standard E60 18" wheels - you might find a spacer that does the trick. Not sure if the offset is for clearance or aesthetics - probably the latter.
