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.
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
With headquarters in Camarillo, California, Wilwood employs approximately 250 people. We have on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Our off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment, to heavy duty original equipment brakes for the U.S. military Humvee.
Wilwood's engineering department uses the latest computer-aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment, to find high-performance and reliability solutions for the most difficult braking tasks. Our extensive inventory of proprietary on-the-shelf components allow us to provide cost-effective solutions for unique brake applications.
Wilwood is ISO 9000 compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.
