Description

The Ksport ProComp Big Brake Kit provides significantly improved stopping power for your vehicle, specifically designed for the Infiniti FX45 (2003-2008). This kit integrates new brake technology to substantially reduce brake fade and continually cools the brake pad surface during use. The calipers are CNC machined from aircraft quality billet, making them extremely lightweight at just over 5 lbs each, and feature differential bore configurations with machined-in protection grooves. Key components include aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates. The opposed piston caliper design enhances pad wear and caliper rigidity compared to OEM systems. Stainless-steel brake lines are utilized to prevent expansion under pressure. This kit features a 2-piece disc assembly for reduced rotating and unsprung weight. The unique slot design on the rotors helps expel gas and pad debris faster, while the cross-drilled rotors offer superior cooling, making them recommended for daily driven vehicles. Each rotor is heat-treated and balanced for optimal performance. The kit includes the necessary mounting components and hardware. Note that this kit fits 2WD vehicles only unless otherwise stated. It is important to ensure compatibility with your specific vehicle configuration.
