StopTech BMW 12-13 335i/14-15 435i w/ M Sport Brakes 370mmx30mm AeroRotor Drilled Zinc Fr Rotor Pair
Stoptech aerorotor replacement kits ark are designed to replace your vehicle's original factory rotors; while retaining the factory brake calipers. although the ark is the same diameter and thickness as the factory rotors; it offers improved cooling; braking; and handling. the directional; floating aerorotors allow independent expansion of the rotor and hat without "coning;" thanks to elongated drive pin holes. ark components include aerorotor friction rings with patented internal vane design; pre-assembled to billet aluminum aerohats with directional stand-offs that optimize cooling airflow. the patented aerorotor vane design pushes up to 80 percent more air than factory rotors for better cooling and reduced fade on the track. the aircraft-grade aluminum hats and 2-piece aerorotors are up to 8 pounds lighter than stock rotors; allowing faster acceleration and deceleration; and improved handling. stoptech aerorotors are available slotted or cross-drilled. these slots or
