The Wilwood DynaPro 4R front drag brake kit trims rotating weight for drag cars that still see the street. GT48 directional-vane, Spec 37 alloy vented rotors measure 12.88 inch by 0.81 inch and weigh about 10.2 pounds each, mounted to lightweight forged aluminum hats on the factory hubs. Radial-mount DynaPro 4R four-piston aluminum calipers weigh roughly 4.1 pounds each with stainless pistons and quick-access pad pins, and BP-20 SmartPads give strong cold bite with fade resistance when hot. A minimum 17 inch wheel is required, and a stainless braided flexline kit is sold separately.
