Wilwood DynaPro radial rear drag brake kits deliver high-torque stopping power with a substantial weight savings over the OE brake components. Dynamic-mount steel rotors weigh only 5.7 lbs. each and attach to the OE hubs with lightweight forged aluminum hats—using a T-nut mounting system that allows the rotor to move independently of the hat during heat cycles. This eliminates stress at the mount points and the subsequent rotor distortion that can otherwise occur with fixed-mount steel plate rotors. Dynamic-mount rotors also assure full release from the pads to run true and drag-free down the track. Parking brakes are also eliminated for additional weight savings. Clamping force is provided by radial-mount DynaPro 4R 4-piston aluminum calipers, weighing in at only 4.1 lbs. each. DP4R calipers feature stainless steel pistons and bridge wear plates, internal bore seals—and allow easy access to the pads for service without removing the calipers from the mount. BP-20 compound SmartPads provide high response and holding power when cold, as well as resistance to fade when hot. The complete package mounts to the OE upright and hub with full bolt-on installation. This Wilwood kit is configured for drag racing only and is not recommended for street use.
