Description

The Ksport Procomp Big Brake Kit offers a sophisticated, bolt-on solution to significantly upgrade your vehicle's braking performance, particularly under the demanding conditions of sustained high heat. Each caliper is precision-machined from a solid billet of aircraft-grade aluminum, ensuring exceptional strength, light weight, and superior corrosion resistance. The calipers also incorporate aluminum pistons, which are vital for maintaining heat resistance and reliable operation under stress. This particular kit features a powerful 8-piston front caliper configuration paired with 330mm two-piece, cross-drilled rotors. The two-piece rotor design contributes to weight reduction while delivering fade-free performance and consistent grip, suitable for both spirited driving and occasional track use. The opposed piston caliper design enhances pad wear and rigidity compared to OEM components. Included are D.O.T. compliant stainless-steel braided brake lines, which eliminate line expansion under pressure, leading to a quicker pedal response and a firmer, more confident pedal feel. The kit comes standard with SC5 Street Pads (NAOC Ceramic), engineered for optimal street and occasional track performance, offering reduced brake dust (by 50% or more), lower noise, and less rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. Customization options for caliper colors (Orange, Red, Black, Yellow) and premium finishes (Silver, Gold, Titanium, Glassy/Hard Anodized) are available, with over 20,000 custom color finishes possible. This kit is specifically designed for the 2002-2008 Mazda 6 (including Mazdaspeed models). Please verify fitment for your specific vehicle year, make, model, and trim. If fitment is uncertain, it is recommended to consult with a sales representative to confirm compatibility before purchase. In the event of an incompatibility issue stemming from a sales team recommendation, the company will work to resolve the situation and may waive restocking fees if the item is returned in like-new condition.
