I bought the wheels from another poster who was selling here. They are 20" OEM 300Ms 275 front and 315 back. The rear hub holes had to be bored out from 72.5 mm to 74.1 mm to fit the X5 since the wheels themselves fit an X6M. The actual look is similar to the 20" 214s. As in, they stick out a hair past the fender without flares and however it will definitely look more sporty with the flares and is highly recommended by most posters here. I also have 20mm H&R spacers on the rear which push the wheels out abit.

Ask daripper where he purchased his rep. wheels. The rep. wheels will not need any boring out work (they are made to fit the X5) and seem to be a good way to go. He can also update you on the wear and tear of his reps. since he has had them now for a few months.
