- For centering the adapter on a 57.1 mm hub, use a Barzetta 60.1/57.1 hub centric ring.
Use a hub centric ring to ensure that the adapter is properly centered on the car. Choose a hub centric ring that has the same outer diameter as the inner diameter of the adapter (60.1 mm) and the same inner diameter as the diameter of your car's axle.
With this adapter, you can reduce the offset in a car with a 4 x 100 bolt pattern by shifting the wheel outwards by 25.4 mm. The bolt pattern stays the same. The stud bolts and nuts (thread pitch: 1.5 mm, thread diameter: 12 mm) for mounting the wheel on the adapter are included in the delivery. However, the bolts for installing the adapter on the car's hub are not included. Please use the car's own bolts. If the adapter is especially thin, you may have to shorten the bolts or purchase bolts with lower heads.
This fine SteyrTek adapter is made of high-quality aluminium. For racing only.
