Brembo 12-20 GS350 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black HA

This is the Brembo Rear GTS Big Brake Kit for your 2012-2020 Lexus GS350. It's a complete rear brake upgrade designed to give you more stopping power and better heat management than the factory setup. If you're looking to improve your GS350's braking performance, especially for spirited driving or track use, this kit is a serious consideration.

At the heart of this kit are the Brembo 4-piston calipers, which offer a larger piston area to generate more clamping force. These calipers are paired with 345x28mm two-piece rotors. The two-piece design helps reduce unsprung weight and allows for better thermal management, as the rotor ring can expand and contract independently of the hat. The rotors themselves are drilled, which helps dissipate heat and gasses, keeping your brakes cooler and more consistent under heavy use. The black caliper finish and drilled rotor pattern give your GS350 a distinct, performance-oriented look behind the wheels.

This kit includes everything you need to get your rear brakes upgraded, including the calipers, rotors, and likely the necessary mounting hardware and brake lines to ensure a proper installation. Brembo is well-known for its high-performance braking components, and this Big Brake Kit is built to their standards. While installation is more involved than a simple pad and rotor swap, it's designed to fit your GS350 without major modifications, making it a straightforward upgrade for a shop or experienced DIYer.
