Brembo 4KC.9009A PISTA 4 TY5 2-Piece Rear Brake Discs 380x28mm

The Brembo 4KC.9009A PISTA track-focused brake disc system delivers professional-grade stopping power for high-performance applications. This 2-piece floating disc design features a 380mm outer diameter with a 28mm thickness, engineered to withstand the extreme thermal demands of track racing and aggressive street driving.

Key Features:

• 2-piece floating disc design reduces unsprung weight and allows for thermal expansion
• 380mm diameter x 28mm thick rotor provides exceptional heat capacity and fade resistance
• 54mm center bell configuration (TY5 hat style) for precise fitment
• High-carbon cast iron disc material optimized for consistent friction and wear characteristics
• Directional curved vane design maximizes cooling efficiency under extreme braking conditions
• Designed for rear axle installation in performance brake system upgrades

Brembo's PISTA series represents the pinnacle of their racing brake technology, incorporating design elements proven in motorsport competition. The 2-piece construction separates the friction ring from the aluminum hat, reducing rotational mass while improving heat dissipation. This configuration also allows the disc to expand and contract independently during heat cycles, minimizing stress and extending service life.
