Ordered a '21 M50i with 22" 758i wheels. I'd rather have the 22" 757 wheels that are only offered on the 40i model. The wheel specs are the same in diameter, width and offset. Anyone know if swapping them would present a problem? I might consider a trade if anyone has a brand new set of 757 wheels. My new M50i will be delivered the week of 30 November.
