What size wheel spacers?

Hi,

I tried search in the forums, but couldn't find an exact answer. I am currently running Alufelgen CS7 with Hankook V12 in these sizes:

Front: 19x8.5 ET35, 235/35/19
Rear: 19x9.5 ET35, 265/30/19

What is the optimal size wheels spacers I can use for front and back to achieve supreme looks with zero rubbing? Any pics would be greatly appreciated. Car is E90 Pre-LCI xi.

Thank you.

May be quicker and more accurate to measure yourself. General rule of thumb is measure the gap between the shoulder of your tire and the inner fender well, then back it off about 1/4" for clearance. You can do 1/8" if you accept that you may have to roll your fenders.

Off the top of my head for that spec wheel: 12mm is a pretty safe bet, 15mm may be pushing it, 20mm would probably require rolling the fenders.

Thank you for your input. I will go for the 12mm spacers in the rear.

Hello-

What spacer would you recommend on a pre lci e92 xdrive with msport 193m's 18inch? Tires are stock RF at 255/40/18 rear and 225/45/18 front?

Will 15mm rear and 12 front be ok? or if i want to upgrade to the 313s at 19" set up will 12mm rear and 10 front be a better option? thanks

15mm rear and 12mm front is a very safe bet for pre LCI, your stock wheels are only 8" wide in the front and 8.5" wide in the rear. You could probably run 15mm front and rear without a problem, but again, the best fit will come from measuring to see exactly where it is going to sit in the fender. Don't have to worry as much about turning clearance on stock wheel/tire setups either since they are pretty forgiving.

How about when I upgrade to 313m 19 inch?

the front will be the same and the rear will poke just 4mm more from the 193m

It'd be safer to measure for yourself so you can get the right size for your own car instead of relying solely on somebody else's word.

Just throw some stuff in the trunk, get a couple friends/family members to sit in the back and measure like so:

Also important to remember to get longer wheel bolts to match your new spacers. For safety.
