Description

The Ksport Procomp rear big brake kit is engineered as a sophisticated bolt-on upgrade to significantly enhance braking power, particularly under sustained high-heat conditions. The calipers are constructed from a 1-piece billet aircraft-grade aluminum, offering a lightweight yet exceptionally strong and corrosion-resistant housing. They incorporate aluminum pistons, which provide superior heat resistance compared to standard materials, ensuring consistent performance. The kit features 380mm two-piece rotors, available in either drilled or slotted options, with drilled rotors recommended for daily driven vehicles due to their cooler operating temperatures. The two-piece design contributes to reduced rotating and unsprung weight. Included in this kit are Ksport's SC5 street brake pads, formulated for optimal performance in street and occasional track use, offering reduced dust and noise. The kit also comes with D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure, leading to quicker pedal response and a firmer pedal feel. Carbon steel caliper brackets ensure the larger calipers bolt directly to the OEM mounting locations.
