Description

Constructed from a solid billet of aircraft-grade aluminum, the calipers offer exceptional strength, light weight, and resistance to corrosion. The inclusion of aluminum pistons further enhances heat management, ensuring consistent operation. This kit features a 4-piston caliper design for the rear, which is crucial for improving pad wear and increasing caliper rigidity compared to OEM components. Ksport also offers customization options for rotor type (slotted or cross-drilled) and caliper color to match your aesthetic preferences. Included are D.O.T. compliant stainless-steel braided brake lines, which reduce line expansion under pressure for a quicker pedal response and a firmer pedal feel. The kit comes standard with SC5 Street Pads, formulated for optimal braking performance in street and occasional track use, offering reduced dust and noise. Ksport Big Brake kits are built to order and typically require 4-6 weeks for production and delivery. It is important to note that Ksport Big Brake kits are designated for "OFF ROAD USE ONLY" unless explicitly stated otherwise, and are intended for competition/off-road use limited to formally sanctioned racing organizations.
