Brembo 03-08 SL500/SL550/09-12 SL550 Rear GT BBK 4 Piston Cast 2pc 328x28 2pc Rotor Drilled-Red

The 328x28mm two-piece rotors in this Brembo GT Big Brake Kit are designed to handle the heat generated by hard braking, especially on heavier vehicles like the Mercedes-Benz SL-Class models this kit is made for. This kit focuses on the rear axle, giving you a significant upgrade over the stock setup. The calipers themselves are a four-piston cast design, which means they offer more clamping force than a typical two-piston caliper, helping to improve stopping power and feel.

Brembo is well-known for its braking components, and this kit uses their GT series technology. The two-piece rotor construction is notable because it allows the rotor and the hat to expand and contract independently as they heat up and cool down. This helps to reduce the risk of rotor warping over time, which is crucial for maintaining consistent braking performance. The rotors are drilled, which helps to dissipate heat and gases, further contributing to a more stable and effective brake pedal, even under demanding conditions. This kit is a substantial upgrade for owners looking to enhance the braking performance of their SL500, SL550, or later SL550 models.

When installing a big brake kit like this, it's important to ensure you have the correct supporting components. While this kit focuses on the rear, you'll want to consider the condition of your front brakes and brake fluid. Always refer to the manufacturer's installation instructions for specific details on mounting the calipers and rotors, and for any recommended brake fluid types to get the most out of this performance upgrade.
