Description
Wilwood Dynapro Radial Front Drag Kit 12.88 Vented 15-23 Mustang
This DynaPro4R Drag Race front brake kit is configured with GT48 directional vane Spec 37 alloy vented iron rotors for optimized thermal stability and durability on drag cars that will also see street use. DP4R race kits deliver high torque stopping power with a substantial weight savings over the OE brake components. These 12.88” x .81” rotors weigh only 10.2 pounds each. Lightweight forged aluminum hats provide additional weight savings to mount the rotors to the OE hubs. Clamping force is provided by radial mount DynaPro 4R four piston aluminum calipers weighing in at only 4.1 pounds each. DP4R calipers feature stainless steel pistons, internal bore seals, stainless steel bridge wear plates, and e-clip style pad retaining pins to allow quick and easy access to the pads without removing the calipers from the mount. BP-20 compound SmartPads provide high response and holding power when cold, and resistance to fade when hot. The complete package mounts to the OE spindle and hub with full bolt-on installation. A minimum size 17” wheels are required along with a stainless steel braided flexline kit available separately.
