Big Brake Kit with Forged Aluminum Calipers

The calipers are constructed from a solid billet of aircraft-grade aluminum, providing lightweight strength, corrosion resistance, and featuring aluminum pistons for superior heat management and uncompromised operation. This kit includes CNC-machined carbon steel caliper brackets that allow for direct bolt-on installation to your OEM caliper bracket location. The Procomp system utilizes two-piece rotors, contributing to a lightweight design that offers fade-free performance and effective grip during track use, while also ensuring comfortable operation for daily driving. It comes standard with SC5 Street Pads, which offer optimal braking performance for street and occasional track use, significantly reducing brake dust and noise compared to race pads. Additionally, DOT-compliant stainless-steel braided brake lines are included, which prevent expansion under pressure for a quicker pedal response and a firmer pedal feel over stock rubber lines. This specific rear kit is designed for the 2006-2013 Lexus IS250 and features 4-piston calipers with 330mm slotted rotors. Ksport offers customization options for caliper colors and rotor types (slotted or cross-drilled), with slotted rotors recommended for track use and cross-drilled for daily driven vehicles. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
