Description

This comprehensive kit includes dual calipers with a 4-piston configuration, paired with 356mm floating brake discs. The kit comes complete with Ksport's SC5 Street Pads, durable carbon steel caliper brackets, a striking polished titanium handbrake, and high-performance stainless steel braided brake lines. The braided lines reduce expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport offers customization options for the brake discs, allowing you to choose between slotted or cross-drilled rotors. Cross-drilled rotors are recommended for daily driven vehicles as they offer better cooling, while slotted rotors are suggested for track-focused applications. This big brake kit is designed as a complete bolt-on system, ensuring everything needed for installation is included. The product is built to order, with production and delivery typically taking 4-6 weeks. It is specifically designed to fit 2010-2013 Mazda 3 models. While the provided list may not be exhaustive, Ksport Industries' website features a full vehicle fitment search tool to confirm compatibility with your specific trim and configuration.
