Rear Brake Kit with 4-Piston Calipers

This rear kit features lightweight, one-piece calipers CNC-machined from aircraft-grade billet aluminum, incorporating a differential bore configuration and opposed piston design for improved pad wear and rigidity over OEM components. The kit includes two-piece rotors, available in slotted or cross-drilled options, to provide lightweight, fade-free performance. Slotted rotors are recommended for track use, while cross-drilled rotors are better suited for daily driving due to cooler running temperatures. The calipers are equipped with aluminum pistons for superior heat resistance and feature stainless-steel brake lines that prevent expansion under pressure, leading to quicker pedal response and a firmer pedal feel. Included with the kit are NAOC Ceramic SC5 Street Pads, offering optimal braking performance for street and occasional track use. These pads significantly reduce brake dust and noise while minimizing rotor wear, with an optimal operating temperature range of 194°F - 1022°F. This Ksport Procomp Big Brake Kit is specifically designed to fit the Subaru Impreza WRX GRB chassis from 2008-2014. Please note that Ksport Big Brake kits are built to order, and production and delivery typically take 4-6 weeks.
