Description

The Ksport Supercomp Big Brake Kit represents an extreme brake upgrade, engineered to deliver superior stopping power for your BMW 3 Series (1992-1998 E36 models including 320i, 323i, 325i, and 328i). This sophisticated, bolt-on system integrates larger calipers, 356mm rotors, and brake pads, along with increased piston sizes and standard full-floating rotors for enhanced self-centering and reduced drag. Constructed from a solid billet of aircraft-grade aluminum, the one-piece calipers are both lightweight and corrosion-resistant, featuring aluminum pistons for improved heat management. The floating two-piece rotor design allows for slight adjustments, optimizing brake application and performance. This kit comes standard with SC5 Street Pads, offering optimal braking for street and occasional track use, while reducing brake dust, noise, and rotor wear. Additionally, D.O.T. compliant stainless-steel braided brake lines are included, which eliminate line expansion under pressure for quicker pedal response and a firmer pedal feel. Customers can choose between slotted (recommended for track use) or cross-drilled rotors, and a variety of custom caliper color options are available. Please note that this is a built-to-order item and typically requires 4-6 weeks for production and delivery.
