Supercomp 8-Piston Rear Big Brake Kit with 400mm Rotors

The Ksport Supercomp Big Brake Kit offers an extreme rear brake upgrade for the 1998-2002 Saab 9-5, delivering enhanced stopping power. This kit features a SuperComp 8-piston opposed caliper, machined from aircraft-grade billet aluminum, designed for reduced brake fade and consistent cooling. The opposed-piston design significantly improves pad wear and caliper rigidity compared to OEM systems. It also includes a 400mm x 36mm 2-piece floating disc assembly, which reduces rotating and unsprung weight. The floating design mitigates thermal stresses, preventing disc warping, while the unique slot design on the rotor expels gas and pad debris efficiently and reduces braking noise. Key components include aluminum caliper pistons for corrosion resistance, high-temperature seals, and stainless steel brake pad wear plates. The stainless steel brake lines resist expansion under pressure, ensuring consistent performance. The kit includes replacement calipers, rotors, pads, brake lines, and all necessary hardware for a bolt-on installation without modifications. Rotor options include cross-drilled for cooler operation and recommended for daily drivers, or slotted for more track-focused use. This SuperComp system comes standard with a 12-month warranty covering manufacturer defects. Ksport also offers brake pad choices, including SC5 Street pads for daily driving and RC1 Race Pads for extreme track conditions.
