Show original supplier description
The Ksport Dualcomp Big Brake Kit provides a significant rear braking upgrade for the 2014-2016 Mazda 6. This system includes 4-piston calipers paired with 13-inch diameter slotted rotors, designed to dissipate heat more effectively and improve braking consistency under demanding conditions. The slotted rotor design helps to clear away brake dust and gases, maintaining optimal contact between the pad and rotor surface. As a specialized brake component, professional installation is recommended to ensure proper fitment and function. The kit's components are designed for direct bolt-on application to the specified Mazda 6 models, providing a noticeable improvement in braking performance and feel.
