Racingline Locking Wheel Nuts for Stud & Nut Kit – M14x1.50
If you’ve fitted a Racingline Stud & Nut conversion kit to your car, the next sensible step is protecting that investment. The Racingline Locking Wheel Nut set adds a simple but effective layer of security against wheel theft, which is especially worthwhile if you’ve upgraded to a set of quality alloys.
What’s Included and How It Works
The kit replaces one standard Racingline wheel nut on each corner of the car with a locking version. Each locking nut has a unique head pattern that can only be undone using the supplied chromed steel key. Without the key, the nut can’t be removed using ordinary sockets or tools, which deters opportunistic theft.
Fitting is straightforward and takes only a few minutes per wheel. Simply remove one of your existing Racingline nuts and replace it with the locking nut, torqued to the same specification.
Choosing the Correct Seat Type
It’s important to match the locking nut seat type to the wheels you’re using. The seat is the part of the nut that contacts the wheel, and using the wrong shape can damage the wheel or cause the nut to come loose.
- Tapered Seat – the most common fitment for aftermarket alloy wheels.
- R13 Ball Seat – typically used on genuine VAG (Volkswagen, Audi, SEAT, Skoda) wheels made before 2020.
- R14 Ball Seat – fitted to most genuine VAG wheels from 2020 onwards.
If you’re unsure which seat type applies to your wheels, check your wheel manufacturer’s specifications or use the vehicle lookup on the Racingline Shop to confirm.
