Wilwood 140-14103 Details

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

Specs

Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
