Remove and refit your wheels regularly? Then you’ll know how frustrating the factory wheel bolts can be! Lining up the bolt holes, bashing your callipers with the wheel, trying to avoid cross-threading the bolts – all while balancing the weight of the wheel.

The MMR Performance stud and nut conversion kit solves all these problems, giving a stronger fixing method than using the OE wheel bolts. Plus, they’re a much quicker method to swap wheels for motorsport and track use too. For all cars with M14 x 1.25 nuts

M14 x 1.25 heat-treated high carbon steel stud with chrome plated finish.

Converting your car to our stud and nut kit is a simple and reversible upgrade that will speed up your wheel changes. Our stud and nut kit also allows for the safe use of different spacer size setups without the risk of running out of bolt threads. All MMR studs are finished in a beautiful midnight-black gloss anodising and both conical and ball seat lug nuts are available to suit either factory or aftermarket wheels.

We offer two different stud lengths, depending on your fitment:
70mm Stud: No spacers, or up to 10mm spacer
80mm Stud: Spacers between 10mm to 20mm

We also offer two different nut types, depending on what wheels you are running: Ball seat nuts or Conical seat nuts. Please check which type your wheels require, it’s important to get it right! Note that most OEM wheels use the Conical seat nuts.
