[GregW / Oregon]

I just sold my RG4s to a guy whose putting them on his E92 M3. I did comparative measurement and test fitting today, and found they are very close. With 5mm spacers on the front only the outer face of the wheel will be in ths same plane as the stock 19s, but the wheels are 1/2" wider.

By measuring the overall width (out-to-out) of the wheels, then subtracting the back space (distance from mounting hub face to rear of wheel), I calculated the amount the face of the rims protruded from the hub as follows:

Stock
F: 9 7/16 - 5 3/4 = 3 11/16
R: 10 7/16 - 6 1/16 = 4 3/8

RG4
F: 9 15/16 - 6 7/16 = 3 1/2
R: 10 7/8 - 6 1/2 = 4 3/8

I then fit the wheels on the car and measured clearance to the shocks/struts. It was 3/8" in front (5/8" with spacer) and 1 1/4"+ in the rear.

Overall pic here looks a little wierd because of the very wide angle lens and the fact the suspension is drooping. Following photos are of rear, front, and front with 5mm spacer.
