Must order quantity 2 to do both of the calipers found on the front wheel.

ZRAC is a very focused and limited product range that features the trademarked HIT™ (High Initial Torque) technology which simply translates into a higher initial coefficient of friction for more more initial bite than the XRAC. But it doesn't stop there, this is combined with an extremely high peak friction for an amazingly powerful brake system. The intent is to offer more performance options for Pro level racing as well as seasoned club racers who prefer the characteristics of a flatter torque curve. Feel and feedback at the lever is superb providing excellent control during late braking corner entrances while it's thermally stable friction characteristics maintain linear progression to peak power under maximum pressure. ZRAC also features the trademarked Array Cooling™ technology to reduce interface temperatures under severe thermal load conditions. This is a highly specialized new product with a limited production range exclusive to late model Sportbikes and Billet GP type race calipers.
