I've got macht schnell 10mm and the rogue 15mm ones, and have no problems at all. The lighter design of the rogue ones is pretty cool too.

I've had no problem with my H&R spacers, but then again, they're only 3mm.

That was me...

Basically I was using a 10mm H&R that worked fine with OEM BMW rims but since I was running a taller Hoosier R6 on my TRM MT1 track rims that day I made a last second change from 12mm to 10mm at the rear to avoid rubbing.

I bought the spacers from Turner and to their credit they have big bold warnings about using 10mm spacers because they have an additional lip on them that smaller and bigger H&R spacers don't have.

The problem for me was that the bevel on the OEM BMW rims are deeper than on the TRM MT1 rims therefore the 10mm spacer did not sit flush on the MT1 rims. I never thought it would be a problem because I assumed the two rims would be the same...if it works for one it should work for the other right? Wrong assumption...

Lesson learned, whatever spacer/rim combo you are using take a feeler gauge and make sure there is no gap between the spacer and the rim before mounting them. If the spacer is only 1mm off the rim you won't be able to see it very easily and the result could be disastrous...

Same thing ALMOST happened to me. I had a 10mm spacer in the rear with my MT1s and studs. Luckily, I mounted the track wheels before leaving the house. After about 5 miles, driving about 65mph on the highway, I felt a vibration from the rear that I knew wasn't right. I pulled over and decided to remove the spacers right there. Vibration gone.

Later after more research, I discovered the same thing...the MT1 need at least a 12mm spacer to work. I order the VAC spacers after recommendations and haven't had a problem since. I'm going on at least 6 track days with this setup. Never a problem.
