Slimline 3 Piston 330mm Front Big Brake Kit

The Ksport Slimline 3 Piston 330mm Front Big Brake Kit is engineered for drivers seeking significantly improved braking performance and response. This kit addresses the common issue of aftermarket big brake kits not fitting wheels with aggressive offsets or limited caliper clearance. Ksport developed the Slimline caliper to be significantly thinner than traditional multi-piston calipers, allowing it to fit within the tight spacing required by many factory or custom wheels. Key components of this big brake kit include lightweight, two-piece 330mm rotors that can be specified as either slotted or cross-drilled. Cross-drilled rotors are recommended for cooler operation on daily driven vehicles, while slotted rotors are suggested for track-focused applications. The kit utilizes 3-piston calipers, offering enhanced clamping force. Carbon steel caliper brackets, precision CNC machined, ensure a direct bolt-on fit to the vehicle's original mounting points. The included NAOC Ceramic SC5 street pads provide a balance of braking performance for daily driving and occasional track use, while also reducing brake dust and noise compared to race pads. To further enhance braking feel and consistency, the kit incorporates DOT compliant stainless-steel braided brake lines. These lines prevent the expansion common in stock rubber lines under pressure, leading to a firmer pedal and quicker response. Ksport Big Brake kits are built to order, and customers should allow 4-6 weeks for production and delivery. This kit is designed for the Mazda 3 from 2004-2009, with specific fitment details available via the vehicle search tool on Fitment Industries.
