Doesn't Rub, Perfect Fitment.
2015 M235 (N55) Doesn't rub at all. Some people have had that problem, there definitely is some wiggle room when mounting, just make sure to get it as center as possible and your crank seal is protected for a fraction of the price compared to Euro aftermarket brands

Good Fit
It was a job. But I did it when I changed the tensioner pully. You're kind of blind when you trying to put the bolts back in the harmonic balancer. Nevertheless just what the doctor ordered

Good cheap insurance
Got one of these for my N55 and N54. Fitment is good had no issues with install. Torque specs are 20nm for the two bolts holding the crank guard. And 35nm for the harmonic balancer. (N54/N55)
