The Ksport Supercomp Big Brake Kit represents the pinnacle of Ksport's braking upgrades, engineered for the BMW 1989-1995 E34 5 Series (525i, 530i, 535i, 540i). This kit is designed as a direct bolt-on solution to significantly enhance your vehicle's stopping performance. It features Ksport's most extreme caliper, rotor, and brake pad combination to deliver unparalleled braking force. This particular Supercomp kit includes substantial 421 x 36 mm slotted rotors paired with high-performance 8-piston calipers in a striking orange finish. The larger surface area and increased piston count allow for more consistent and powerful braking, reducing stopping distances and improving heat dissipation under demanding conditions.
