Description

The Ksport Slimline 3-Piston Big Brake Kit (BKMZ330-312SO) offers a significant upgrade over stock braking systems, specifically engineered to address the clearance issues often encountered with aggressive wheel fitments. Its standout feature is the Slimline Caliper design, which mimics the thickness of OEM single-piston calipers, ensuring compatibility with most factory wheels and those with minimal brake caliper clearance. This allows enthusiasts to install a high-performance big brake kit without necessarily needing to purchase new wheels. Constructed with lightweight, two-piece rotors and robust CNC-machined carbon steel caliper brackets, this kit provides a direct fit to your vehicle's OEM caliper bracket location. It comes standard with Ksport's SC5 Street Pads, designed for optimal braking performance on the street and for occasional track use. These pads are formulated to reduce brake dust by over 50% compared to race pads, minimize noise, and reduce rotor wear, with an optimal operating temperature range of 194°F - 1022°F. Enhancing pedal feel and response, the kit includes D.O.T. compliant stainless-steel braided brake lines. These lines eliminate the expansion common in stock rubber lines under pressure, resulting in a firmer pedal and quicker reaction time. For customization, the rotors are available in either a slotted or cross-drilled finish. Cross-drilled rotors are recommended for daily drivers as they run cooler, while slotted rotors are suggested for track-focused vehicles. This Ksport Big Brake Kit is built to order, with production and delivery typically requiring 4-6 weeks. It is specifically designed to fit the 2016-2018 Mazda MX-5 Miata models. Fitment should always be confirmed prior to purchase, and if a fitment issue arises from a recommendation made by the sales team, the item can be returned under like-new condition with no restocking fees.
