Bigger Rotors, More Heat Capacity for the Explorer ST Front Axle
Step up the front brake performance on your 2020-2023 Ford Explorer ST with the RFK.640.02 Rotora Street Challenge Front Brake System. A 6-piston RF606 forged caliper paired with a larger 380x35mm 2-piece floating rotor means more swept area, more heat capacity, and better fade resistance during sustained hard braking compared to both the factory setup and the smaller RFK.640.01 option.
