Hi

Can't seem to find a definitive answer to this question. Has anyone tried fitting the 20" 666M M3/M4 Competition package wheels on a F30? I want to have them fitted with 275/30R20 and 245/35R20.

I have some friends who fitted those tyres on style 303M wheels, with dimensions 8.5J ET 25 and 10J ET41. With these dimensions the car had an aggressive stance with the wheels lining up very well to the arches (not sticking out); and no touching on the tyres.

The 666M wheel is 9J ET29 and 10J ET40. In my understanding then, with reference to the 303M wheel, the fronts will sit in roughly the same position and stance (wider wheel should roughly compensate for the higher offset); and the rears will sit 1mm further into the arch. These movements are so minimal that I don't see why the wheels shouldn't be a direct fit.

Can someone advise if they have tried it, and send some pictures?
