ccmguy8,
Your car is gorgeous. I will have to see it in person sometime this summer to stay motivated. I've been lusting for a set of these wheels, regardless of the vehicle that they go on (including my Subaru Outback

). What tire size are you running? Also, considering that you are running a square setup and the E9 track width is more narrow than the front, did you consider spacers in the rear as well? Lastly, Is the spacer in conjunction with a hubcentric ring to account for the E39 74.1, or is that integrated with the spacer. Thanks!
