Brembo 05-13 Mazda3 Front GT BBK 4 Piston Cast 2pc 330x28 1pc Rotor Drilled-Black

This Brembo GT Big Brake Kit for your 2005-2013 Mazda3 front end includes everything you need to significantly upgrade your braking performance. You get a pair of Brembo's 4-piston GT calipers, two 330x28mm one-piece drilled rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory brake components with a much more robust setup, offering improved stopping power and heat management for spirited driving or track use.

The calipers are cast aluminum, which keeps them strong yet relatively lightweight. They feature a 4-piston design, meaning more clamping force is applied to the rotor surface compared to a typical 2-piston factory caliper. The rotors are 330mm in diameter and 28mm thick, providing a larger surface area and greater thermal mass to absorb and dissipate heat. The drilled pattern on the rotors helps to vent gases and water away from the pad surface, maintaining consistent braking performance even under heavy use. This kit is a direct bolt-on replacement for the factory setup, meaning no modifications are needed to your existing brake lines or mounting points.

When installing a big brake kit like this, it's always a good idea to check your brake fluid level and consider a flush with high-temperature fluid to get the most out of the new components. This kit is a substantial upgrade for Mazda3 owners looking for a noticeable improvement in braking feel and fade resistance.
