Brembo 12-20 GS350 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type3-Silver

This Brembo GT Big Brake Kit for the rear of your 2012-2020 Lexus GS350 includes everything you need to significantly upgrade your braking system. You get a pair of Brembo's 4-piston GT calipers, two 345x28mm two-piece rotors with a Type 3 slotting pattern, high-performance brake pads, and all the necessary mounting hardware and stainless steel brake lines. This kit is designed to replace your factory rear brake components with a much more robust and capable setup.

The calipers are cast from aluminum for a good balance of strength and weight, and they house four pistons that apply even pressure across the brake pad for improved stopping power and feel. The two-piece rotors are a notable upgrade; the cast iron friction ring is separate from the aluminum hat. This design helps manage heat more effectively and reduces unsprung weight, which can contribute to better overall vehicle dynamics. The Type 3 slotting pattern on the rotors is specifically chosen to help clear dust and gas away from the pad surface, ensuring consistent performance even under heavy braking conditions. This means you get a more reliable and powerful stop, whether you're on the street or pushing your car on the track.

Installing a big brake kit like this is a significant modification, and it's designed to work as a complete system. The included stainless steel braided brake lines are a crucial part of the upgrade, as they resist expansion under pressure much better than rubber lines, leading to a firmer pedal feel and more precise braking control. This kit represents a substantial investment in your GS350's performance and safety, offering a dramatic improvement over the stock braking hardware.
