Installation guide
These studs replace your original wheel bolts, making installation straightforward. If you prefer professional fitting, Nforcd can install this kit at our Warwickshire workshop. Request a fitting quote at Sales@nforcd.com.
- Remove wheels. Clean hub threads and the short ends of the new studs using brake cleaner. Ensure threads are free from dirt and grease.
- Confirm the stud shank passes through the brake disc holes and does not bottom out on the disc.
- Apply a thin coat of high temperature threadlocker such as Loctite Blue 2422 to the short end of the stud.
- Using a 6 mm Allen key, screw the short end of the stud into the hub until you reach the shank.
- Do not overtighten. Tighten to around 30 ft-lb or 40 Nm.
- Allow approximately three hours for the threadlocker to cure. Refit wheels with the new 19 mm nuts and torque to the factory wheel bolt specification.
- Recheck nut torque after around 30 minutes of driving once the assembly has warmed through.
