All calipers are constructed from a solid billet of aircraft-grade aluminum, ensuring lightweight strength and corrosion resistance, while aluminum pistons provide superior heat management and reliable operation. This kit features a one-piece caliper construction with opposed piston designs that improve pad wear and caliper rigidity over OEM components. For the rear, it utilizes lightweight 4-piston aluminum calipers for 13" and 14" systems, or 2-piston calipers for 11" and 12" systems. The kit also includes D.O.T. compliant stainless-steel braided brake lines, which reduce line expansion under pressure for quicker pedal response and a firmer pedal feel. Included are NAOC Ceramic SC5 Street Pads, offering optimal braking performance for street and occasional track use, with reduced dust and noise compared to race pads. For customization, calipers are available in various standard colors like Orange, Red, Black, and Yellow, with options for premium high-polish finishes and custom color matching. All Ksport Big Brake kits come with CNC-machined carbon steel caliper brackets that allow for direct bolt-on installation to the OEM caliper bracket location. These kits are built to order, with a production and delivery time of 4-6 weeks.
