Brembo 97-04 986 Boxster S Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled- Yellow

The 345x28mm, two-piece rotor design is a key feature of this Brembo GT Big Brake Kit, specifically for the rear of your 97-04 Porsche Boxster S. This setup replaces your factory braking components with a substantial upgrade, aiming to improve stopping power and heat management under demanding driving conditions. The kit includes four-piston calipers, which offer more clamping force than stock, working in conjunction with the larger, vented rotors to dissipate heat more effectively.

Brembo uses cast iron for the caliper bodies, a well-built material known for its strength and thermal stability. The two-piece rotor construction allows for better thermal expansion and contraction, reducing the risk of warping compared to a single-piece rotor. These rotors are drilled, which helps to vent gases and moisture away from the pad surface, maintaining consistent braking performance. The calipers come in a bright yellow finish, adding a visual performance element to your vehicle.

This kit is designed as a comprehensive rear brake upgrade. When installing a big brake kit like this, it's important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. It's also a good idea to consult the manufacturer's installation guide for specific procedures and any recommended accompanying hardware or brake fluid.
