Brembo 4KC.9019A PISTA 4 TY5 2-Piece Rear Brake Disc Rotor 380x28mm

The Brembo 4KC.9019A PISTA 4 TY5 is a high-performance 2-piece rear brake disc designed for serious track and racing applications. This premium rotor features a 380mm diameter with a 28mm thickness, engineered to deliver exceptional stopping power and thermal management under extreme conditions.

Key Features:

• 2-piece floating disc design reduces unsprung weight and allows for thermal expansion
• 380mm diameter x 28mm thickness provides massive heat capacity and fade resistance
• 54mm center bell mounting pattern (TY5 configuration)
• Manufactured from high-carbon cast iron for optimal friction and wear characteristics
• Directional vane design promotes efficient heat dissipation and cooling
• Professional-grade construction for endurance racing and track day use

Brembo's PISTA (track) series represents the pinnacle of braking technology, utilizing the same materials and engineering expertise that powers Formula 1 and professional motorsports. The 2-piece design separates the friction ring from the aluminum center bell, reducing rotating mass while maintaining structural rigidity and thermal stability during sustained hard braking.
