Brembo 06-11 GS300 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type1-Silver

This is the Brembo Rear GT Big Brake Kit for your 2006-2011 Lexus GS300. It's a complete rear brake upgrade designed to give you more stopping power and better heat management, especially if you push your car hard or plan on track days. Brembo is well-known for making top-tier braking components, and this kit represents their GT line, which is a step up from their standard offerings.

What you get here is a pair of robust 4-piston cast aluminum calipers. These calipers clamp down on larger 345x28mm two-piece rotors. The two-piece design helps with heat dissipation and can make rotor replacement easier down the line. The rotors themselves are slotted, which helps to clear out brake dust and gasses that can build up between the pad and rotor surface. This slotting pattern, Brembo's Type 1, is designed for optimal performance without excessive noise. The silver finish on the calipers gives a clean, performance-oriented look behind your wheels.

This kit is a significant upgrade over the stock braking system. The larger rotor surface area and the multi-piston caliper design mean more even pressure distribution and better thermal capacity. This translates to more consistent braking performance, especially during repeated hard stops where factory brakes might start to fade. Installation will involve replacing your factory calipers and rotors, and you'll want to ensure you have the correct brake fluid for bleeding the system afterward. It's a substantial upgrade that really changes how your car feels when you need to slow down.
