I have M sport 18" rims, not lowered on E92.

The BMS website shows and E93 with 10 mm front and 18 mm rear and an E92 with 10 mm front and 15 mm rear (non-M sport).

Which wheel spacer do I use for the rear? 15 or 18 mm?

Both will work!

Is there a preferred setup with my 18" M Sport rims and say, up to a 265 width rear?

[XstheticMotorsports]

yea, both will work! Go with the 18mm.

Sorry to come back to this thread. Should I stick with the original 18 mm rear spacer recommendation if I plan on changing my tires to Michelin PSS? I ask because the more square sidewall has me worried 18 mm may rub.

You will be fine with an 18mm spacer on the 193m rims. I had PSS 265 on 9.5 et33 with a 10mm spacer and rubbed a little bit, but I took the spacer off and was fine. Those end up being the same offset with your 18mm spacer.

Check out my picture thread, I'm running 12mm up front and 20mm in the rear and I'm lowered like crazy. The only time I rub is when I go up inclines into parking lots or ramps. And even then it's minimal. a light scuff as opposed to a hardcore tire sidewall rubbing lol. I have the same 193M wheels.

Wow, nice photos! Those might convince me to actually get coilovers one of these days. Did you remove the stock mudflap things from the front bumper?

Do you rub the fronts or the rears? I was also only planning on a 10 mm front. Are your tires still stock?

Check your gap, and purchase the right spacers for your setup.

You can always contact them and get their input as well.

I used a pair of digital calipers and did this, but I couldn't get an accurate measurement because I have a rounded sidewall on my tires.

Thanks man! I did remove the little flap things from the bottom, I just tore them off lol they came off super clean almost like they were designed to rip off by choice.

The tires are stock sir! 225s up front and 255s in the rear, bridgestone Potenza re050a. You can run a 12mm in the front with no rubbing problems whatsoever!

Tore them off? Wait, how are they attached?

Do you think the 12 mm will be okay for a 235 front width tire, which is what I plan to get down the road.

I am running pretty aggressive myself on my E90

I have 265/30/19 on 19x9.5 35 offset with 10mm spacer. Barely, and I mean barely rubbed. So I rolled fender gently. This is basically a 25 offset. Now after a light roll I can probably go to 12mm.

I am running 19x8.5 in the front with offset 35 and 12mm spacer and I know I can go 15mm easily. with 235/35/19.

If your 18's are 18x8 then you can easily 20mm on the rear without rubbing at all. For the front if you have a 18x8 you can run 15mm easily with no rubbing.

Thanks for the advice. I am almost certain I will be choosing 12 mm front and 18 mm rear. I think I can push the limits without getting right up to that limit.

definitely go with 12mm up front as the hub on bmws can extend as much as 11mm making the 10mm spacer not sit flush. I had this issue and took a grinder to the hub to remove the 1-2mm of hub to make it sit flush. In retrospect, i should have gone with 12.5mm spacers and will be ordering them when i swap my brakes in the coming month. I like the bms/turner motorsports spacers as they have a lip on the back for a screwdriver to get them off easily.

I'm running 20mm spacer in the front on a 8.5x18 making it offset 20 with one finger gap lowered all around.
