Brembo 15-21 WRX (VA) Front GT BBK 4 Piston Cast 326 x30 1pc Rotor Slotted Type-1-Red

The cast iron caliper body on this Brembo GT Big Brake Kit is a solid foundation for serious stopping power, designed specifically for the 2015-2021 Subaru WRX (VA chassis). This kit replaces your factory front brakes with a much more robust setup, featuring four-piston calipers that clamp down on larger 326x30mm one-piece rotors. The calipers are finished in a striking Type-1 Red, making them a standout visual upgrade as well as a functional one.

Brembo chose a cast iron construction for the caliper bodies because it offers excellent thermal stability and rigidity, which is crucial for maintaining consistent braking performance under heavy use. The rotors are a one-piece design, meaning the rotor and the hat are a single unit, simplifying installation and reducing weight compared to two-piece rotors. These rotors are also slotted, a design choice that helps to sweep away brake dust and gases that can build up between the pad and rotor surface. This slotting pattern is Brembo's Type-1, known for its effectiveness in keeping the braking surface clean and ensuring reliable performance, especially during repeated hard stops.

This kit is a significant upgrade over stock, intended for WRX owners who push their vehicles hard, whether on the track or during spirited driving. It's a complete front brake solution, offering a substantial improvement in both braking feel and fade resistance. When installing, ensure you have the necessary tools and refer to the manufacturer's instructions for proper assembly and bleeding procedures to get the most out of this high-performance brake system.
