DualComp Rear Big Brake Kit

The Ksport DualComp Big Brake Kit is a high-performance rear brake upgrade designed for the Mazda 3 models from 2004-2009. This kit features a sophisticated dual-circuit design with four pistons – two dedicated to the primary foot brake and two for the handbrake system, offering enhanced stopping power and control. It utilizes floating brake discs to improve heat dissipation and reduce rotor stress. This kit is a complete bolt-on system, providing all necessary components for installation. Customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to better cooling, while slotted rotors are advised for track use. The stainless-steel brake lines included in the kit minimize line expansion under pressure, resulting in a quicker pedal response and a firmer pedal feel compared to stock rubber lines. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. Fitment is extensive, covering a wide range of Mazda 3 vehicles from 2004 to 2009. The product listing includes a fitment search tool to ensure compatibility with specific trims and configurations. Fitment Industries emphasizes confirming fitment before ordering, and they offer assistance if their sales team recommends an incompatible setup, promising to rectify any errors on their part with no restocking fees for such instances, provided the item remains in like-new condition.
