Description

The Ksport Dualcomp Big Brake Kit is an advanced rear braking system featuring a unique dual caliper design. This innovative setup utilizes a single 4-piston caliper, with two pistons dedicated to the foot brake and the other two for the handbrake, ensuring independent operation for each function. This complete bolt-on system comes with everything required for installation, including calipers, lightweight two-piece rotors, performance brake pads (SC5 Street Pads), a polished titanium handbrake cylinder and lever, and all necessary hardware. The included SC5 Street Pads provide optimal braking performance for street use and occasional track days, with reduced dust and noise compared to race pads. Additionally, the kit includes D.O.T. compliant stainless-steel braided brake lines, which enhance pedal response and feel by preventing line expansion under pressure. Customization options are available for the brake calipers, including standard painted colors like Orange, Red, Black, and Yellow, as well as premium high-polish finishes in Silver, Gold, and Titanium. Over 20,000 custom color finishes are also an option. Buyers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to better cooling, while slotted rotors are suggested for track use. Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks. This specific kit is confirmed to fit the 2014-2016 Mazda 6 GS trim. While the system is designed as a true bolt-on upgrade, buyers are advised to verify fitment for their specific vehicle configuration.
