Show original supplier description
The Ksport Procomp 8-Piston Big Brake Kit is engineered as a sophisticated, direct-fit upgrade to significantly enhance your vehicle's braking power, especially under sustained high-heat conditions. The calipers are precision-machined from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet exceptionally strong and corrosion-resistant construction. They utilize aluminum pistons, which offer superior heat resistance compared to traditional materials, maintaining uncompromised operation even under demanding use. For customization and performance tuning, Ksport offers the Procomp rotors in your choice of cross-drilled or slotted configurations. Cross-drilled rotors are recommended for daily-driven vehicles as they run cooler, while slotted rotors are suggested for track-focused applications. Included with the kit are Ksport's SC5 Street Pads, a NAOC Ceramic compound that provides optimal braking performance for both street driving and occasional track use. These pads are formulated to significantly reduce brake dust (by 50% or more compared to race pads) and minimize noise and rotor wear. The optimal operating temperature range for these pads is between 194°F and 1022°F. Furthermore, the kit incorporates D.O.T. compliant stainless-steel braided brake lines. These lines are crucial for preventing hose expansion under pressure, leading to a quicker pedal response and a firmer, more consistent pedal feel compared to stock rubber lines. The calipers are also available in various standard colors (Orange, Red, Black, Yellow) with options for premium finishes like Silver, Gold, Titanium, and custom colors, allowing for a personalized aesthetic. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks.
