Motorsport Hardware (BMW/MERCEDES) 20-Piece Wheel Stud Conversion 78mm Length (12x1.5) with Black Conical Seat Nuts

Great quality product... I installed them as soon as I got them. They went on without any issue. I had to look up the torque specs for the studs (use red lock tight). Then torque the lug nuts also to spec also.

Top notch quality. Very happy with this kit.Thanks

Easy to install good quality happy with the purchase
