Key Features

This Brembo Front GT BBK combines advanced technology and thoughtful engineering to elevate braking performance. Key features include:

• 4-piston calipers for increased clamping force and improved pedal feel
• Two-piece cast rotors measuring 326 mm diameter by 30 mm thickness for enhanced heat dissipation
• Slotted Type 1 rotor design to improve pad bite and reduce brake fade
• Durable black finish for corrosion resistance and a sleek appearance
• Optimized for direct bolt-on installation with factory mounting points
• Compatible with OEM brake pads and hardware for ease of maintenance
• Engineered to reduce unsprung weight compared to traditional one-piece rotors
• Designed to improve braking consistency during aggressive driving and track conditions

Construction & Design

The Brembo Front GT BBK features a two-piece rotor design that combines a cast iron braking surface with a lightweight aluminum hat. This construction enhances thermal management by allowing the rotor to dissipate heat more efficiently, reducing the risk of warping and brake fade during extended use. The 4-piston calipers are cast from high-strength aluminum alloy, providing excellent rigidity and resistance to flex under heavy braking loads.

The rotors are precision-machined and feature slotted grooves that help evacuate gases, dust, and water from the pad surface, ensuring consistent contact and improved braking performance. The black finish on the calipers and rotors not only protects against corrosion but also adds a refined, aggressive look that complements the sporty character of the 86, BRZ, and FR-S.

Installation & Fitment

This Brembo Front GT BBK is designed for direct fitment on 2013–2020 Toyota 86, 2013–2020 Subaru BRZ, and 2013–2016 Scion FR-S models. Installation requires no major modifications, as the kit uses factory mounting points and hardware compatibility. Professional installation is recommended to ensure proper torque specifications and brake system bleeding for optimal performance and safety.

What's Included

• Two 4-piston Brembo front calipers
