Installation Notes
The supplied studs are designed to replace the original studs, not to convert a wheel-bolt application into a stud-mounted arrangement. Before installation, check the wheel-stud count, thread specification, required stud length and spacer compatibility with the vehicle's hubs and wheels.
Wheel spacers alter track width and wheel position. Ensure adequate clearance and confirm that the installation complies with the requirements applicable to your vehicle.
