Wilwood Dynapro Radial Rear Drag Kit 12.90in Drilled 15-23 Mustang

This Wilwood DynaPro Radial Rear Drag Kit gives you the components to upgrade your 2015-2017 Ford Mustang for serious drag strip duty. Inside this kit, you'll find a pair of DynaPro 4R four-piston aluminum calipers, each weighing just 4.1 pounds, along with dynamic mount steel rotors that are a mere 5.7 pounds each. These 12.90-inch rotors are drilled and designed to attach to your OE hubs via forged aluminum hats using a T-nut system. This setup allows the rotor to expand and contract independently during heat cycles, preventing stress and distortion that can happen with fixed-mount rotors. The dynamic mount design also ensures the rotors fully release from the pads, so they run true and drag-free down the track.

The DynaPro 4R calipers are well-built with stainless steel pistons, internal bore seals, and stainless steel bridge wear plates, making pad service easy without needing to remove the caliper. The kit comes with BP-20 compound SmartPads, known for their strong holding power when cold and fade resistance when hot. This entire package is configured specifically for drag racing, offering substantial weight savings over your stock brake components by eliminating the parking brake system. The installation is a full bolt-on affair, mounting directly to your OE upright and hub.

Because this kit is designed for competition, it's not recommended for street use. You'll need a minimum of 17-inch wheels to clear the components, and a stainless steel braided flexline kit is available separately to complete the setup.
