Floating Disc Big Brake Kit with Slotted Rotors

This sophisticated bolt-on upgrade features a lightweight, one-piece caliper constructed from aircraft-grade billet aluminum, weighing just over 5 lbs. The caliper boasts differential bore configuration, CNC machining, aluminum pistons for enhanced heat resistance, high-temperature seals, and stainless steel brake pad wear plates. Its opposed piston design significantly improves pad wear and caliper rigidity compared to OEM systems. The kit utilizes a two-piece disc assembly, reducing both rotating and unsprung weight. Many applications offer a floating disc option to mitigate thermal stresses and prevent warping. The unique rotor slot design not only reduces braking noise but also efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Ksport recommends slotted rotors for track use and cross-drilled rotors for daily-driven vehicles. Included are D.O.T. compliant stainless steel braided brake lines, which eliminate line expansion under pressure, leading to quicker pedal response and a firmer pedal feel. The kit comes standard with SC5 Street Pads, offering optimal braking performance for street and occasional track use, with reduced dust, noise, and rotor wear. Caliper brackets are made of CNC-machined carbon steel to ensure a direct bolt-on installation to OEM caliper bracket locations. Fitment is specifically for the Subaru WRX STI from 2015-2021. Ksport Big Brake kits fit 2WD vehicles only unless otherwise stated. While the product page indicates fitment for a wide range of vehicles, including specific Subaru WRX and WRX STI trims, it is crucial to confirm compatibility for your exact vehicle configuration. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. If fitment issues arise due to a recommendation from the sales team, returns may be accepted without restocking fees under specific conditions.
