At 1.46 lbs., this is the lightest axle clamp & floating rotor mount kit available. 3.00 x 46 Splined Clamp (For 42 Splined Sprint Car Rear Ends). The "T-Nut" mounting system allows the rotor to expand & contract independently of the mount as the rotor goes through temperature changes.
The WILWOOD SPRINT CAR ROTOR MOUNT HUB KIT is ideal for vehicles with INBOARD transmissions, designed to elevate the rotor mount's center of gravity for improved brake performance and handling.
