A friend of mine is looking into wheels for his 2001 540i ( 6 Speed Sport)

He mentioned "Installing Fikse wheels and Yokohama tires next month, may change out the shocks as part of that."

any advice? I mentioned that he should retain the OEM diameter so that he doesn't mess with the speedometer/odometer or run into any issues. I also recommended BBS LM's .

what is the best wheel for this model?
