Rothsport's quick release is CNC machined from 7075 anodized aircraft alloy. It is very light and solid, with zero play and is removed and installed with one hand. The Engagement is elliptical without splines which guarantees the wheel will clock properly every time. The adapter bolts directly between a Momo, OMP, or Rothsport hub and the steering wheel, positioning the wheel 2-3/8 inches closer to the driver. This product is designed for racing use.
