This rear system is designed as a Drag Race only part, and features 4 S4 4-piston calipers mounted to a 11 inch x 1 inch directional, 2-piece slot, drill, zinc plated rotor. There Is NO Park Brake In This System! This is designed specifically for heavy, fast drag cars that rely on their brake to launch or stage the car. The rear systems are specific to the housing end being used, if you are unsure of what ends you are working with please contact us direct. Note: Your axle flange will need to be turned down to 5.75 inches for this system to work. These systems are available in a variety of piston sizes. The larger piston area, 1.75 inches, will provide maximum clamping force, but can cause long pedal issues due to large volume requirements. A smaller 1.375 inch piston option was introduced, and has been a very popular option in classes such as NMRA True Steet where the cars will see limited street use. These rear systems are designed for racing only. If used on the street, due to brake bias change, be sure to spend some time to make sure adjusted correctly. Note: This system comes equipped with a high friction pad that is optimized for drag race applications. These pads often produce more dust and noise.
