This premium rotor features a 380mm outer diameter with a 28mm thickness and 54mm center bore (54a specification), delivering exceptional stopping power and heat management for demanding driving conditions.

Key Features:

• 380mm diameter x 28mm thick rotor dimensions for maximum braking surface
• 2-piece floating design reduces unsprung weight and allows thermal expansion
• 54mm center bore (54a specification) for precise hub fitment
• PISTA racing specification for track and competition applications
• Type 3 (TY3) rotor configuration optimized for rear axle performance
• Engineered with Brembo's racing-derived materials and construction
• Improved heat dissipation reduces brake fade during intense use

Brembo's PISTA line represents their top-tier racing brake components, featuring advanced metallurgy and precision manufacturing. The 2-piece design separates the friction ring from the aluminum hat, reducing rotational mass while maintaining structural integrity under extreme thermal stress. This system is ideal for serious track enthusiasts and professional racing applications requiring maximum braking performance and consistency.
