Overview

It features larger calipers, rotors, and brake pads compared to the Procomp kit, along with increased pistons and standard full-floating rotors for enhanced self-centering. The calipers are constructed from a solid billet of aircraft-grade aluminum, providing lightweight strength and corrosion resistance, and utilize aluminum pistons for improved heat management.
Show original supplier description
This kit incorporates larger calipers, rotors, and brake pads than their Procomp line, featuring an increased piston count and standard full-floating rotors that promote better self-centering within the caliper. The calipers themselves are manufactured from a single billet of aircraft-grade aluminum, ensuring exceptional strength, light weight, and resistance to corrosion, while aluminum pistons are employed for superior heat tolerance. Key features include a "Lightweight Forged One-Piece Caliper" constructed from aerospace-quality aluminum for uniform strength. The "Floating Two-Piece Rotor Design" allows the outer rotor section to shift slightly, improving self-centering, reducing brake drag, and optimizing pad application for enhanced performance. Standard "SC5 Street Pads (NAOC Ceramic)" are included, offering optimal braking for street use and occasional track days, with a significant reduction in brake dust, noise, and rotor wear, effective in temperatures between 194°F - 1022°F. Additionally, D.O.T. compliant stainless-steel braided brake lines are standard, providing a quicker pedal response and firmer pedal feel by preventing line expansion under pressure. Customers can choose between slotted or cross-drilled rotors, with cross-drilled recommended for daily drivers due to better cooling, and slotted for track-focused vehicles. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. The available fitment includes various Subaru Impreza WRX and WRX STI models from 2008 to 2021. Fitment confirmation is crucial to avoid ordering errors; if fitment is confirmed by the sales team and the item does not fit, Ksport will accept returns with no restocking fees, provided the item is in like-new condition. If an issue arises due to an error on Ksport's part, including incorrect sales team recommendations, they will work to make it right.
