6-Piston Big Brake Kit with Slotted Rotors

The Ksport ProComp Big Brake Kit is a sophisticated, complete brake upgrade for your 1993-1998 Subaru Impreza STI, engineered to significantly enhance stopping power, especially under sustained high-heat conditions like track use. This kit features robust 6-piston calipers, each constructed from a single billet of aircraft-grade aluminum. This mono-piece design ensures exceptional light weight, unparalleled strength, and resistance to corrosion. The calipers are equipped with aluminum pistons, which offer superior heat resistance and maintain uncompromised operation during aggressive driving. Reinforced carbon steel caliper brackets allow these larger-than-OEM calipers to bolt directly onto the existing mounting points without requiring vehicle modifications. The braking performance is further augmented by the 2-piece rotors, which are both vented and slotted. The 380mm (15-inch) outside diameter rotors utilize an aluminum center hat to lower rotational mass, leading to quicker braking response and shorter stopping distances. The 2-piece design also helps mitigate rotor warpage by allowing for less restricted expansion and contraction of the iron braking surface. All caliper seals are heavy-duty, built for sustained high-temperature racetrack use, and the included stainless steel brake lines prevent expansion under pressure, ensuring a firmer and more responsive pedal feel. It requires a minimum wheel diameter of 19 inches (482.6mm) to accommodate the larger caliper and rotor assembly. This kit is ideal for performance and racing driving styles, providing a significant upgrade in braking capability for demanding applications.
