SKU: 20577


Unique design maintains original rotor location. Simply bolt the rotor to the adapter using the Howe t-nuts, then bolt the adapter solid to the hub.

Larger t-nut contact surface distribute braking forces more evenly than other floated designs allowing more uniform expansion and no binding that creates vibration. Floated mounts allow the rotor to expand when hot without distorting resulting in improved pad wear and rotor life.

Improved rotor to pad contact by maintaining a flat surface and lower temperatures. Race tested at harsh braking tracks.  Fit any common 8 bolt on 7” circle racing rotor.

Each hub requires an Adapter (20577), a T-Nut & Bolt Kit (36575N) to secure the rotor to the adapter, and bolts to secure the adapter to the hub.
