I used Turner Motorsports Spacers, 12mm front, 10mm rear, with extended hubs. No problem whatsoever so far...

Yes, mine do, but still. And they are supposedly from a "reputable" company, but they didn't warn me about this incompatibility. Like I mentioned, I learned the hard way, and later on read up on a document on tuner Motorsport that confirmed my speculation that the 10mm won't fit "properly" in the front.

From Turner's website:

Wheel Spacer Tech & FAQ
How To Measure for Spacers
Wheel Spacer Encyclopedia - everything you wanted to know

A note about 10mm spacers: Any 10mm spacer is considered a custom fitment. The stock hubcentric lip on BMWs can stick out by as much as 11mm. A 10mm spacer will bottom-out and leave a gap between the spacer and the hub which seriously compromises safety. The best way around this is using a larger spacer (12mm and larger do not have this issue) or check that the lip sticks out less than 10mm. In some cases you can modify the hub lip to get the 10mm spacer to fully seat on the hub.

10 mm H&R Spacer fits both on front and rear axel.

Respectfully, there are people smoke a pack a day their entire life and never gotten sick, but I wouldn't personally take that risk knowing the damage smoking cigarettes can do to my lungs. And everyone can freely do what they want to their cars - I really don't have problem with that. Just roll with two lug bolts untitqued and I'll just smile and tell you best of luck

I am just a little confused because it seems everyone who has been running spacers are running 12mm and 10mm. Is everyone running the wrong spacer set up?!

Knowing what I know now, it is my opinion that running 10mm in the front is a wrong decision.

i purchased and installed spacers from Burger tuning over the weekend (12mm up front and 10mm in rear). No issues whatsoever. I even reached out to them re these concerns and there is nothing to worry about.

So knowing this now what are your plans on your current 10mm rear set up?

I have H&R springs ready to install when my car arrives. Still deciding on what the right spacer setup might be.

Was interested in why you were suggesting 10mm wasn't right. BruceM's explains it. Like you, I was thinking 10mm but will now reconsider. Thanks for promoting a good thread conversation.

Going to call Turner and ask. The internet word, to the extent it exists, seems to be that the problem can be running 10 in the fronts, not in the rears...

So 10mm at the back wont fit?! Ive gone for 12mm at the front and 10mm at the back.

I went with these based on everyone elses set up and experience so its a bit disconcerting to hear that 10mm might not fit on the back now.

Can someone please clear this up for us ignorant folk!??

Some (many) brands of </= 10mm spacers have a ridge on the inside of the spacer lip that is intended to seat the hat lip but will prevent the spacer from seating completely on the hat on cars with elongated hub lips like the M2 = wobble/vibration. It is possible to modify these type of spacers by having a machine shop grind down that ridge. Since the M2 hub lip (on my car) measures 12mm, it could be a potential problem for spacers up to 12mm thick but conventional wisdom says it is problem for spacers constructed in this manner 10 mm and less. The issue or "problem" is the M2/3/4 have slotted hub lips that are atypically long- with reports up to 14mm. Great for wheel assembly strength, not great for spacers that are not constructed with this in mind.

The Turner spacers have solved this issue by having integrated hub lip extenders. Turner therefore will seat completely flush against the hat = no wobble/vibration.

This is all explained in detail on the Turner website. I am not here to promote Turner or bash any other brand, but not all 10mm spacers are plug n play like Turner.....

if you were holding the two types of spacers in your hand it would be blatantly obvious but damn it is hard to convey easily in words !

This certainly reflects my experience. I have not had even a hint of wobble or vibration with 12mm/10mm, front/back Turner spacers...

Thats a good explanation thank you - I ordered H&R spacers because they were more readily available to me in the UK

These ones

10 at rear here and absolutely no issues whatsoever. Spacer seated 100% flush with wheel. Ive already put about 100km on with them, both street and highway up to 150-160km/h...no vibration or wobble. smooth as silk
These are the Burger Tuning ones by the way.
