MMR Wheel Stud and Lug Nut Conversion Kit – M14x1.25 Thread Pitch

Upgrade your wheel fasteners to a stud-and-nut conversion that is built for speed, confidence and convenience. This M14x1.25 stud conversion transforms wheel swaps, making tyre changes, track day pit stops and garage maintenance faster and cleaner than with standard OE bolts. No more juggling heavy wheels while trying to line up bolt holes. Just hang the wheel on the studs, spin on the nuts and torque to spec. Simple, secure, repeatable.

We run this kit on our own builds and our customers love the difference. Consistent clamping, easier wheel changes and smarter looks thanks to the beautiful midnight-black gloss anodised nuts. It is the performance wheel hardware upgrade that enthusiasts, track day drivers and detail-focused owners keep asking for.

• Helps prevent cross-threading issues common with standard wheel bolts
• Protects brake callipers and discs from accidental knocks during refits
• Reliable, repeatable torque for confident fastening
• Flexible with hub-centric spacers and varying spacer thicknesses
