Bump on this thread since it doesn't have a definitive answer to the OP's original question (nor can I find an answer in any other thread), and I'm contemplating this to get around some understeer that's now in my way as I've increased my skills on the track -- but I would be running this setup full-time since I don't yet want to deal with dedicated track wheels and tires. Will OEM rear 220Ms with OEM rear tires fit on the front of a non-ZCP M3 with no modifications? If so, will they protrude outside the fender, and if so by how much? And will they rub at all, and if so how much wheel lock will it take, and does it just tear up the fender liner or will it damage the tire as well?
