Brembo 08-13 135i (E81/E82/E88) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Red

The 345x28mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, chosen for their ability to handle heat during repeated hard stops. This kit is specifically designed for the rear of your 2008-2013 BMW 135i models (E81, E82, and E88 chassis), giving you a significant upgrade over the factory braking system. The four-piston calipers are built to provide strong, consistent clamping force, which translates to improved stopping power and better pedal feel, especially when you're pushing your car hard.

Brembo's GT BBK is a well-built system that aims to enhance your car's performance braking. The calipers feature a durable red finish, and the two-piece rotor design helps manage heat and reduce unsprung weight compared to a single-piece rotor. The slotted rotor surface is designed to help clear out brake dust and gases, which can improve pad contact and maintain braking performance under demanding conditions. This kit is a comprehensive solution for enthusiasts looking to upgrade their vehicle's braking capabilities for track days or spirited driving.

When installing this kit, remember that it's a significant modification to your braking system. It's always recommended to consult the manufacturer's installation guide for specific details and torque specifications. You'll want to ensure all components are properly seated and secured for optimal performance and safety. This kit is a substantial investment in your vehicle's performance and should be installed by someone familiar with brake system upgrades.
