Brembo 12-20 GS350 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type3-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 your factory setup. If you're looking to improve your car's performance, especially under demanding conditions like track use or spirited driving, this kit is a solid choice.

At the heart of this kit are the 4-piston aluminum calipers. These are larger and more robust than stock, allowing for more pad material and better clamping force. They work with 345x28mm two-piece rotors. The rotors are slotted, which helps to vent gases and dust away from the pad surface, keeping your braking consistent even when things get hot. The two-piece design also helps manage heat and can make rotor replacement easier down the line. The calipers come in a black finish, adding a clean look behind your wheels.

This kit includes everything you need to get your rear brakes upgraded: the calipers, the two-piece slotted rotors, brake pads specifically matched to the calipers, and stainless steel brake lines. The stainless steel lines are a notable upgrade over rubber hoses, as they resist expansion under pressure, giving you a firmer pedal feel. While this is a comprehensive kit, always refer to the manufacturer's installation instructions for specific details and any additional hardware or fluids that might be recommended for your vehicle.
