Description

The Ksport Dualcomp Big Brake Kit offers an advanced Dual Caliper solution, engineered with performance driving, drifting, and rally racing in mind. This system utilizes a single 4-piston caliper, ingeniously splitting its function: two pistons engage the foot brake, while the other two operate the handbrake, each with its own independent system. This provides enhanced control and stopping power. The kit includes precisely machined components such as forged, monoblock aluminum calipers, lightweight two-piece slotted or cross-drilled rotors (356mm diameter), SC5 street brake pads, and D.O.T. compliant stainless steel braided brake lines. The caliper brackets are CNC-machined from carbon steel to ensure a direct bolt-on fit to the OEM caliper bracket locations. Additionally, the handbrake features a polished titanium cylinder and lever for improved aesthetics and control. This comprehensive, complete bolt-on system comes with everything required for installation, including all mounting components and hardware. The included SC5 Street Pads are formulated for optimal braking performance in street and occasional track conditions, offering a significant reduction in brake dust and noise compared to race pads, with an optimal operating temperature range between 194°F - 1022°F. The stainless steel brake lines prevent expansion under pressure, resulting in quicker pedal response and a firmer pedal feel. This specific kit is designed for the Infiniti FX35 models from 2003 to 2008. Ksport Big Brake kits are built to order, and customers should allow approximately 4-6 weeks for production and delivery.
