1-Piece Aluminum Caliper Kit with Carbon Steel Brackets and

The Ksport Procomp Big Brake Kit offers a sophisticated bolt-on upgrade to enhance your vehicle's braking power, particularly under sustained high-heat conditions. This kit is engineered with 1-piece calipers forged from a solid billet of aircraft-grade aluminum, ensuring lightweight construction, exceptional strength, and resistance to corrosion. The calipers are equipped with aluminum pistons that offer superior heat resistance for uncompromised performance. This system utilizes an opposed piston caliper design, which significantly improves pad wear and caliper rigidity compared to OEM designs. The kit includes CNC-machined carbon steel caliper brackets, facilitating a direct bolt-up installation to your vehicle's factory caliper bracket location. Included with the kit are NAOC Ceramic SC5 Street Pads, which provide optimal braking performance for both street and occasional track use. These pads offer a significant reduction in brake dust (50% or more) compared to race pads, while also minimizing noise and rotor wear. The pads are effective within an operating temperature range of 194°F to 1022°F. For enhanced pedal feel and response, DOT compliant stainless-steel braided brake lines are standard, preventing line expansion under pressure and providing a firmer pedal feel than stock rubber lines. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This specific kit, BKSB150-611CO, is designed for the Subaru Impreza WRX models from 2008-2021 and is available with either cross-drilled or slotted rotors. Cross-drilled rotors are recommended for daily drivers due to their cooler operation, while slotted rotors are suggested for more track-oriented vehicles.
