Just an update on what my deep research has uncovered regarding wheel spacers (just got off the phone w/ H&R who was able to pull up the pre-release documentation for the F30 while I was on the phone - albeit, I had to wait on the line for like 15min):
5mm spacers (fine for front/rear)
10mm spacers (front only)
12mm spacers (front only)
15mm+ spacers (fine for front or rear)
*NEW* - H&R is soon to release a 13mm spacer that will work on the rear for the F30
After a lot of back and forth, I am thinking a 13mm+ spacer is still too much for thge OEM stock setup. I'm fairly certain I will settle on a 5mm spacer for front + rear.
FOTIO - FYI - I was able to cancel my 12/15mm purchase, so will likely go w/ a 5mm setup. Tend to agree with you - stock setup only needs a bit of a spacer to help w/ the flush/classy look.
