Hi, I have 2 RS3's coming off my 1 series. They have very little mileage on them, maybe 4-5000 miles. They are excellent, sticky tires, but not for me anymore that I have stopped autox'ing my 1 series.
On my 1, these fit the rear with Arc 8, 9.5" et 62 and a 5mm spacer. Required fender roll. otherwise stock suspension in the rear. If you don't have a 1M, these are a tight fit. Very sticky, WOT in 1st gear is totally possible without much slippage at all.
These are $293/tire at tirerack.com. Asking $400 for the pair
