BBK 2PC ROTOR, FRONT

The Stoptech Trophy Big Brake Kit (front half, MPN 83.137.4700.74) for the Mazda RX-7 (FD chassis) includes 4-piston calipers, brackets to mount calipers in stock locations, 2-piece floating 332x32mm slotted AeroRotors, pads, and stainless steel brake lines. The Aerowave rotors feature a proprietary low-turbulence airfoil vane design for improved airflow. The hard-anodized hat also has vanes to increase airflow between the hat and rotor, reducing heat transfer to the hub and wheel bearings. The rotors are floated to help avoid warpage and caliper piston knockback, allowing movement of about 0.012 inches.
