Wilwood's Gen II Midget inboard hub & adapter kit provides a basis to provide dynamic rotor mounting of standard 6 x 5.50” bolt pattern rotors. Hub & adapter kits contain: rotor adapter and dynamic rotor mounting bolt kit. Manufactured from high strength aluminum, it provides a lightweight and strong solution for rotor mounting. Gen II hubs offer improved clearance and easier install due to widening of the rotor adapter attachment bolt spacing. Additional T-nuts and bolts are required rotor mounting and are not supplied with the clamp kit.
