Dualcomp Rear Big Brake Kit with 330mm Discs

The Ksport Dualcomp Big Brake Kit is engineered for the rear of the Mazda 6 (2002-2008), offering a significant upgrade in stopping power and control. This kit features a unique dual caliper system utilizing a single 4-piston caliper, with two pistons dedicated to the primary foot brake and the other two for the handbrake, each operating on its own hydraulic circuit. This setup is designed with drifting and rally racing in mind, providing enhanced control. The kit includes lightweight two-piece rotors, CNC machined carbon steel caliper brackets for direct OE fitment, and comes standard with SC5 Street Pads, offering optimal braking performance for street use and occasional track days with reduced dust and noise. The system also incorporates D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure for a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Buyers can choose between cross-drilled rotors, recommended for daily driven vehicles due to better cooling, or slotted rotors, recommended for track use. This is a complete bolt-on system that includes everything necessary for installation: calipers, floating brake discs, brake pads, handbrake, and all required hardware. The kit is Formula Drift legal. Ksport Big Brake kits are built to order, and customers should allow 4-6 weeks for production and delivery. Fitment is extensive, and buyers are encouraged to use the vehicle search tool to confirm compatibility with their specific Mazda 6 model, year, and trim.
