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

The 345x28mm, two-piece rotor design in this Brembo GT Big Brake Kit is a key feature for managing heat during spirited driving. This kit is specifically for the rear of your 2012-2020 Lexus GS350, aiming to significantly improve your braking performance. It replaces your factory setup with a robust 4-piston caliper system and slotted rotors, which help clear out dust and gas to maintain consistent braking force, especially when you push your car hard.

Brembo's GT Big Brake Kits are well-known for their ability to handle the demands of performance driving. The calipers are cast from high-grade materials for strength and durability, and they're paired with these substantial 345x28mm two-piece rotors. The two-piece design allows for better thermal management, as the rotor and hat can expand and contract independently, reducing the risk of warping. The slotted surface on the rotors helps to vent gases and debris away from the pad surface, ensuring optimal contact and stopping power when you need it most. This black caliper finish also adds a clean, aggressive look behind your wheels.

When installing a big brake kit like this, it's important to ensure you have the correct supporting components. While this kit focuses on the calipers and rotors, always refer to the manufacturer's installation guide for any specific hardware or fluid recommendations. This upgrade is designed to provide a noticeable difference in braking feel and performance, giving you more confidence on the road or track.
