Description

The Ksport Supercomp 8-Piston Big Brake Kit represents the pinnacle of braking system upgrades, engineered to deliver unparalleled stopping power directly to your vehicle without requiring any modifications for installation. This sophisticated bolt-on system enhances the capabilities of Ksport's Procomp kit by incorporating larger calipers, rotors, and brake pads, complemented by an increased number of pistons and standard full-floating rotors. The full-floating rotor design allows for slight shifts, improving self-centering within the caliper, minimizing brake drag, and optimizing brake application for enhanced performance. Each caliper in this kit is meticulously crafted from a solid billet of aircraft-grade aluminum, utilizing a one-piece forged construction. This method ensures exceptional strength, minimal weight, and superior resistance to corrosion, surpassing traditional cast or welded caliper designs. The calipers also feature aluminum pistons, which offer improved heat resistance and maintain uncompromised performance even under demanding conditions. For compatibility with the larger OEM caliper bracket locations, the kit includes CNC-machined carbon steel caliper brackets. This kit comes standard with SC5 Street Pads, designed to provide optimal braking performance for both street driving and occasional track use. These pads offer a significant reduction in brake dust (over 50% compared to race pads) and minimize noise and rotor wear, operating effectively between 194°F and 1022°F. Further enhancing the braking system are D.O.T. compliant stainless-steel braided brake lines, which prevent line expansion under pressure, leading to quicker pedal response and a firmer pedal feel. The kit includes 356mm slotted rotors, recommended for vehicles used more frequently on the track. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This specific kit is designed for the 1995-1999 BMW M3. Fitment can be confirmed via the vehicle search bar on the product page, and Fitment Industries offers a fitment guarantee: if their sales team confirms compatibility and the product does not fit, they will accept returns with no restocking fees, provided the item is in like-new condition.
