Macht Schnell Wheel Studs Install

Just did a Macht Schnell wheel stud conversion on my F80, most of my OE lug bolts were getting rounded down by either someone overtightening with an impact or just general wear/tear.

The exact kit I used was:
Macht Schnell Competition Stud Conversion Kit - BMW 75mm / 14x1.25

On to the install...

Car jacked up, having to hammer the wheel w/ a rubber mallet to loosen

Macht Schnell hardware all organized and ready to go on

Applying the supplied blue thread locker (I am not using red to ease removal in the future).

Tightening down with 15mm hex. I got these hand tight, then torqued to 18lb/ft with my torque wrench

All of the studs installed and torqued.

Have to use a 17mm deep socket now to install or remove the lug nuts. I later torque these down to 100lb/ft each.

Front drivers wheel done. Just rinse/repeat 3 more times, and you are good to go!

Hope this thread helps anyone who is thinking of doing this. Install is pretty easy, took about an hour, with much of the time just jacking up the car and mounting / dismounting the wheels.

Cool DIY.

You missed a step. The "maybe I should take a wire brush to my hub" step.
