Brembo 12-20 GS350 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Silver

The 345x28mm, two-piece rotors in this Brembo GT Big Brake Kit are cast from a high-carbon iron alloy, a material chosen for its ability to handle heat without warping. This specific design, featuring a fixed caliper with four opposed pistons, works together with the larger rotor surface to offer a significant improvement in braking performance over stock components. It’s a substantial upgrade for drivers who demand more from their vehicle’s stopping power, especially during spirited driving or when carrying heavier loads.

This kit includes Brembo's GT caliper, a well-built, four-piston unit designed for consistent pressure application across the entire brake pad surface. The caliper is paired with a two-piece rotor assembly, where the rotor disc is separate from the aluminum alloy hat. This construction helps manage heat expansion and reduces unsprung weight compared to a single-piece rotor. The rotors themselves are slotted, a design choice that helps to vent gases and dust away from the pad surface, maintaining a cleaner contact patch and improving braking consistency, particularly under heavy use. The silver finish on the calipers adds a clean, performance-oriented look behind your wheels.

When installing a big brake kit like this, it's important to consider that it's a comprehensive system. This kit is designed to be a direct fit for the intended application, but it's always recommended to consult the manufacturer's installation guide for specific details and torque specifications. Upgrading your rear brakes with a kit of this caliber can make a notable difference in your vehicle's overall braking feel and performance.
