E92 M3 Lug to Stud Conversion

Did the lug to stud conversion for me E92 M3. Had no idea how easy this was going to be. Usually it’s annoying when a car already has studs, but the set up for these was to literally just screw in the studs, adding a little blue loctite at the end. Do all work at your own risk.


  • Jack & stands
  • 5mm hex head
  • Blue loctite
  • Kit I used was the 56mm wheel studs with conical seat lug nuts. The thread pattern is 12×1.5mm

Frankly because of the hex key portion, I thought this kit was a little too long. I think 10mm shorter would have been ideal, as I was unable to install my closed-end lug nuts on these studs, and had to go with their supplied nuts. Obviously, car needs to go up and the wheels need to come off.

I used a little bit of blue loctite on the shorter end of each stud, threading in carefully. Once in place, use a 5mm hex head to apply some torque to the stud. I believe the torque spec is only like 30 lb ft here.

Once all 5 are threaded in, go ahead and mount and torque down the wheel. I think loctite needs roughly 15 minutes to set, so once that is done, that’s literally it.

I thought I had a picture of what the OEM lug was, but I remember it being 61oz. The new set up is 48oz plus whatever the nut will weigh, which will vary based on size and material. I believe the supplied nut was roughly 30oz – so there’s a small gain in weight here, but it’s by far made up for it with how many times I’ve mounted and dismounted these wheels doing the brake jobs already.
