Brembo 12-20 GS350 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-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 performance. You get a pair of 4-piston calipers, two 345x28mm two-piece rotors that are drilled for heat dissipation, caliper mounting brackets, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brake components with a much more robust system, offering improved stopping power and fade resistance, especially during spirited driving or track use.

The calipers are cast from aluminum for a good balance of strength and light weight, and they feature a 4-piston design. This means more clamping force is applied to the rotor surface compared to a typical 1 or 2-piston caliper. The two-piece rotors are a notable upgrade, allowing for better thermal management as the aluminum hat can expand and contract independently of the iron braking surface. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, which contributes to consistent braking performance even under heavy load. Brembo is a well-known name in high-performance braking, and this kit reflects their expertise in creating systems that offer both enhanced performance and durability.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. You may also want to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the kit's capabilities. This kit is a substantial upgrade for the GS350 owner looking for a significant improvement in braking feel and performance.
