3) mounted hitch, (not sandwiched), bolted down with 19mm socket
4) put difuser back on, re-install difuser screws
No vibrations. 30 minutes. Fits perfect. Thule 4 place bike rack installed. I love it! No bikes near or on my car. No garage height issues. Truck accessible.
Happy 2012 135i owner.
So do you not have to trim the underbody panel like the instructions say?
