Show original supplier description
This comprehensive, bolt-on upgrade enhances braking capabilities significantly, making it ideal for track use or aggressive driving. The kit features lightweight, forged one-piece calipers crafted from aerospace-quality aluminum. This construction method eliminates weak points found in cast or welded calipers, ensuring unparalleled strength and resistance to fracturing, warpage, and corrosion. The opposed-piston design ensures even brake pad wear. The lightweight 6061-T6 aluminum center sections reduce rotational mass for quicker brake response and act as heat sinks. For vehicles with more track use, slotted rotors are recommended to manage heat, dust, and gases, while cross-drilled rotors are suggested for daily drivers due to cooler operating temperatures. This specific kit includes 2-pot calipers, suitable for 11” and 12” rear brake systems. The kit includes forged monoblock aluminum calipers, lightweight two-piece rotors (slotted or drilled), SC5 Street Brake Pads, stainless steel brake lines, and all necessary mounting hardware. Please note that Ksport Big Brake kits are built to order, requiring an estimated 4-6 weeks for production and delivery.
