Brembo 4KC.9013A PISTA 4 TY5 Rear 2-Piece Brake Discs 380x28mm

The Brembo 4KC.9013A PISTA 4 TY5 is a high-performance rear brake disc system engineered for track and competition use. This 2-piece floating disc design features a 380mm outer diameter with a 28mm thickness and 54mm center bore, optimized for aggressive braking applications where heat dissipation and weight reduction are critical.

Key Features:

• 2-piece floating disc construction reduces unsprung weight and allows thermal expansion
• 380mm diameter provides increased braking surface area for improved stopping power
• 28mm disc thickness for enhanced thermal capacity and fade resistance
• 54mm center bore (Type 5 mounting) for precise fitment
• PISTA series design optimized for track and racing environments
• Premium Brembo casting and machining for consistent performance

The floating disc design separates the friction ring from the aluminum hat, reducing heat transfer to wheel bearings and hubs while minimizing weight. The TY5 designation indicates the specific bell mounting pattern. These discs are designed to work with Brembo big brake kits and require compatible calipers and mounting hardware.
