Brembo 15-21 WRX Front GT BBK 4 Piston Cast 2pc 332x32 2pc Rotor Slotted Type1-Black

This Brembo GT Big Brake Kit is a complete front brake upgrade specifically for the 2015-2021 Subaru WRX. It replaces your factory front brake components with a much larger and more capable system designed for serious stopping power. If you're pushing your WRX hard on the track or just want the best possible braking performance for spirited street driving, this kit is built to handle it. The kit centers around a pair of robust 4-piston cast aluminum calipers and substantial 332x32mm two-piece rotors.

The calipers are Brembo's GT series, known for their solid construction and ability to dissipate heat effectively under heavy use. They feature a 4-piston design, which means more clamping force is applied to the rotor surface compared to your stock calipers. This translates to improved braking feel and significantly reduced stopping distances, especially during repeated hard braking events. The rotors are a two-piece design, with a cast iron friction ring bolted to an aluminum hat. This design helps reduce weight and allows for better thermal management, as the hat can shed heat more efficiently than a solid one-piece rotor. The friction rings are slotted, which helps to keep the brake pads clean and clear out gases and heat, maintaining consistent performance even when things get hot.

This kit comes with everything you need to perform the front brake conversion, including the calipers, two-piece slotted rotors, brake pads, and all necessary mounting hardware and stainless steel braided brake lines. The calipers themselves are finished in a sleek black, adding a performance look to your WRX. While this is a significant upgrade, it's designed to fit your 2015-2021 WRX without requiring major modifications to the suspension or chassis. However, it's always a good idea to confirm wheel clearance with the specific wheels you plan to use, as larger brake kits can sometimes interfere with wheel spokes.
