Here is the *plan*;
lower 1.25" front and 1" rear
spacers 15mm rear
tires 225/4
5/19 instead of 225/40/19 (I hated the ride of the different sets of 225/40/18 tires I had)?
It did work on my E90.
The F30 stands very high. The diameter of the wheels is 1" larger, so the tire is 0.5" closer to the fender than the E90.
Would it fit?
