Wheel Studs & Nuts guide

Extended studs for spacers

A spacer pushes the wheel out, which leaves less thread for the nut. Our bullnose studs are 60mm long in grade 10.9 steel, and the rounded tip locates the nut and helps stop cross-threading.

Toyota 86 ZN6 and Subaru BRZ ZC6: M12 x 1.25, 14.3mm knurl, 11mm longer than the factory 49mm stud. Suits front and rear hubs.
Mazda MX-5 NA, NB, NC, ND and Abarth 124: M12 x 1.5, 20mm longer than the factory 40mm stud, in 12.8mm or 14.7mm knurl to suit your hub. Pack of 8.

Singles are available for the 86 and BRZ and the MX-5 if you need to replace one or top up a set.

Open-ended lug nuts and lock nuts

An open end lets a longer stud pass right through the nut, so you get more thread contact. That makes these nuts a good match for extended studs and spacers. They are steel with a black E-coating, a 60° taper seat and a 17mm hex. Choose the thread that matches your studs: M12 x 1.25 or M12 x 1.5. The set of 20 covers four five-stud wheels, and a single nut replaces a lost one. The multi hex lock nut set gives you four lock nuts and a key socket.

Before you fit

Check your wheels use a 60° taper seat, and torque to your car's factory wheel nut spec. Pair these with our wheel spacers. We recommend installation by a licensed mechanic.
