STREET AXLE PACK, DRILLED AND SLOTT

Optimized for exclusive track use, focusing on lighter weight and specific design features for extreme track requirements. Incorporates StopTech's Balanced Brake Upgrade® approach, patented rotor cooling vanes, and stiff caliper designs. STR calipers are 20% lighter due to extra machining, and rotors have 50% more air airflow with a special mounting system for the rotor hat. Pad knock-back is eliminated by using floating hardware between the hat and disc. Trophy calipers are only available in dark-grey military-spec hardcoat. Race calipers do not use dust boots on the caliper pistons and are only sold for racing or exclusive track activity. For any street use, the Trophy Sport kit should be selected. Periodic rebuilds and regular fluid changes are strongly advised. This kit has been discontinued by Stoptech/Centric.
