Overview

The Ksport DualComp Big Brake Kit is a performance upgrade designed for the 2002-2004 Subaru Impreza STI with OEM Brembo brakes. This kit features a dual-caliper system where two pistons are dedicated to the foot brake and two are dedicated to the handbrake, each operating independently. It is a complete bolt-on system that includes calipers, floating brake discs, brake pads, and all necessary hardware for installation without modifications.
Show original supplier description
Its innovative dual-caliper design ensures independent operation for both the foot brake and handbrake systems, providing enhanced control and stopping power. This kit is designed as a direct bolt-on replacement, requiring no modifications for installation. The system utilizes a 4-piston caliper with 330mm (13" diameter) drilled, vented, 2-piece rotors featuring a fixed hat construction. The opposed-piston caliper design significantly improves pad grip and minimizes uneven wear, while aluminum caliper pistons resist corrosion and reduce weight. Reinforced carbon steel caliper brackets ensure a secure fit to existing mounting points. Benefits include reduced rotational mass and quicker braking response thanks to the 2-piece rotors with aluminum centers, which also mitigate warpage. Heavy-duty caliper seals are built for sustained high-temperature use, and stainless steel brake lines prevent expansion for improved pedal feel and responsiveness. The kit requires a minimum wheel diameter of 432mm (17"). This kit is specifically designed for the 2002-2004 Subaru Impreza STI models equipped with OEM Brembo brakes.
