83 Compound is a super high torque compound that requires finesse. The torque curve rises with heat to handle the most extreme applications. 83 Compound is no longer made. When current stock is depleted, this compound will no longer be available.
93 Compound was developed after the 83 compound, with higher initial bite and better release characteristics for improved trail braking into corners and easier modulation at threshold braking. It is also kinder to the discs, polishing discs smooth even under severe conditions. Pad life is also very long. Requires finesse to prevent over-slowing the car. 93 Compound is no longer made. When current stock is depleted, this compound will no longer be available.
