OMP Steering Wheel Hub Adapter Kits allows for the quick and easy installation of an aftermarket steering wheel to your race car. The 6-bolt hub pattern will fit all OMP steering wheels, along with many Sparco, MOMO and other steering wheel brands with a 6-bolt hole pattern (except wheels from Nardi and Personal). Adapter kits are designed to bolt directly to your car's existing steering column (installation hardware, such as nuts/bolts, not included).
