These anodized aluminum spacers are designed to bolt between your 6-bolt steering wheel hub and your 6-bolt steering wheel. The fixed height moves your wheel 60mm (2 3/8") closer to the driver. Dual bolt pattern fits both OMP/MOMO/Sparco/Raid 6x70mm (2 3/4") wheels and Nardi/Personal 6x74mm (2.9") wheels. For racing use only; not intended for highway use. Sold individually. Each includes mounting hardware for each end of the hub.
