KB6 + 400mm Brake Kit represents the flagship configuration of the KB6 lineup, engineered for high-performance vehicles, high-output power builds, and aggressive driving demands. The large 400mm disc delivers exceptional braking torque and thermal capacity, maintaining consistent performance under extreme conditions.

The KB6 six-piston caliper features a 6061-T6 forged aluminum two-piece construction, ensuring structural stability even under very high braking pressure. The six-piston layout provides strong, evenly distributed braking force with a firm and confident pedal feel—ideal for high-performance street and track-oriented applications.

The 400mm disc offers outstanding heat capacity and cooling efficiency, significantly reducing the risk of brake fade during repeated high-speed braking. This size typically requires 20-inch or larger wheels, with select OEM large-diameter wheels supporting direct installation.

Custom caliper finishes and KCDesign logo options allow the brake system to become a visual centerpiece behind the wheels.

This complete brake kit includes calipers, 400mm brake discs, dedicated mounting brackets, and stainless steel brake lines, designed for direct bolt-on installation using factory mounting points.

Recommended Wheel Size: Compatible with 20-inch and larger wheels
