Boost Logic Billet Aluminum Girdle For R35 GTROur billet girdle is made from 7000 series aluminum to add significant rigidity to the VR38 motor. 7000 series aluminum is strong, with a strength comparable to many steels, and has good fatigue strength and average machinability.

My favorite BMW car mount.
This is my favorite mount for BMWs. I have them on two cars (X4M and a 328), but I always modify the mount and install a metal ball (purchased here on Amazon) so I can mount an ESR Wireless charger.
This combo is the best charging mount and system I have ever tried

sturdy mount nice fit
fit nicely and magnet is strong using the included metal disc to put inside phone case. was missing instructions but figured it out. you have to screw in the small set screws until it is snug. using a longer hex key made it easier.

Be patient screwing the 4 screws lol, but other than that. It feels heavy duty and fit like a glove. I LOVE it!!
