Works Bell steering wheel adapter, allows you to convert Momo/Sparco pattern to Nardi/Personal pattern, and vice versa. This allows you to bolt up aftermarket steering wheels to hubs with the different bolt patterns.

Made from BILLET aluminum. 12mm thick, the adapter also doubles as a spacer, bringing the steering wheel closer for more direct steering input.

These are stack able spacers which can also be used in conjunction with Works Bell quick release adapters and hubs.
