Use this adapter plate to install an OMP, Sparco, or MOMO* steering wheel (6x70mm bolt circle) on your quick-release steering hub. This aluminum adapter fits the "American" three-bolt pattern (three 5/16" bolts on a 1.75" circle) used on our Hex Type Quick-Release Steering Wheel Hubs.
We also offer a 6-Bolt Steering Wheel to European Quick-Release Hub Adapter to fit the "European" 10-32 on 50mm pattern used on our our SPA Design Splined Quick-Release Steering Wheel Hubs.
Note: This adapter has a 60mm OD centering "spigot" designed to fit into the center hole in the steering wheel. Many MOMO and Sparco racing steering wheels do not have the center hole for this platform to fit into. If your 6-bolt wheel does not have a center hole, you will need to modify the wheel or the adapter and mounting bolts.
