Show original supplier description
This rear kit features 304mm two-piece slotted rotors paired with 2-piston calipers constructed from a solid billet of aircraft-grade aluminum. This material choice ensures lightweight, unparalleled strength, and freedom from corrosion, while the aluminum pistons offer superior heat resistance. The kit includes Ksport's SC5 Street Pads, formulated with NAOC Ceramic compound for optimal braking performance on the street and during occasional track use. These pads offer a significant reduction in brake dust and noise compared to race pads, with an optimal operating temperature range of 194°F - 1022°F. Complementing the calipers and rotors are D.O.T. compliant stainless-steel braided brake lines, which eliminate expansion under pressure to provide a quicker pedal response and a firmer pedal feel over stock rubber lines. The kit utilizes CNC-machined carbon steel caliper brackets that allow the larger Ksport calipers to bolt directly onto the OEM caliper bracket locations. This big brake kit is built to order, with production and delivery typically taking 4-6 weeks. Ksport offers a wide range of caliper color options, including standard painted colors (Orange, Red, Black, Yellow) and premium high-polish finishes (Silver, Gold, Titanium), with extensive custom color possibilities available.
