Supercomp Rear Big Brake Kit

The Ksport Supercomp BMW 1M Coupe Rear Big Brake Kit represents the pinnacle of Ksport's braking upgrade technology, engineered to deliver unparalleled stopping power without the need for vehicle modifications. This sophisticated kit is designed as a direct bolt-on solution, integrating advanced brake technology to significantly reduce brake fade and continuously cool and refresh the brake pad surface during braking. At the core of this system are the extreme lightweight, forged one-piece aluminum calipers. Unlike cast or welded calipers, their one-piece construction from a solid billet of aerospace-grade aluminum ensures uniform thickness and strength, eliminating weak spots that can lead to failure. These calipers feature opposed-piston designs with aluminum pistons for superior heat resistance and consistent pad wear, high-temperature seals, and stainless steel brake pad wear plates. The kit includes standard SC5 Street Brake Pads, offering optimal performance for street and occasional track use, with reduced dust and noise. The Supercomp kit utilizes two-piece, 15.7-inch slotted rotors that are significantly lighter than OEM rotors, reducing rotational mass for quicker response. The floating rotor design allows the outer section to expand and contract independently, minimizing warping due to heat buildup and improving self-centering within the caliper for reduced drag. For those seeking maximum performance on the track, an upgrade to RCI Race Pads is available, offering superior stopping power at higher operating temperatures. D.O.T. compliant stainless steel braided brake lines are also included, preventing hose expansion under pressure for a firmer pedal feel and quicker response. The kit comes complete with forged monoblock aluminum calipers, lightweight two-piece rotors (slotted or drilled), SC5 street brake pads, stainless steel brake lines, and all necessary mounting components and hardware. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks.
