Spacers

Vegetable · 07-04-2018, 09:21 PM

Just ordered a 2019 M4 with 437M wheels. I was looking to bring them out a bit for a more flush look.. I currently have BMS 10mm front and rear 15mm spacers on the rear of my 435i.. Can I transfer these to my new M4 or will they not be compatible? Or do I need a different set of spacer sizes altogether.

Thanks!

Same exact fitment. You will be just fine.

15 on the rear you say? so you didn't find that a bit aggressive on your 435? members on this forum sometimes report using 15 in the back, I always wondered about damage from rocks and grit to the side of the car. did you ever see that?

It wasn't too bad. Many people do 18 mm in the rear. I had a few tiny scuffs from rocks after 120,000 miles, but a worthwhile trade off for the looks.

Due to the fenders you will want 15mm front and 12mm rear to get things perfectly flush. 15mm on the rear will poke a little bit.

I had 15 squared. I didn't think the rear poked out. The rear bumper cover didn't get peppered either.

12 rear 15 front makes everything perfectly square, at least that's what EAS told me when I ordered my spacers anyway for my M3 a couple years ago. Looks perfectly square to me with that setup.

I have 15mm all around on 666M ZCP Wheels... It looks perfect but the car is stock height. If I'm lowering I'm doing 12mm in the rear.

Assume everyone using spacers are also sourcing longer wheel bolts, correct? What size bolts work best with this set up?
