Brembo 4K3.9010A PISTA 4 TY3 2-Piece Rear Brake Rotors 380x32mm

The Brembo 4K3.9010A PISTA 4 TY3 are high-performance 2-piece rear brake discs engineered for track and racing applications. These rotors feature a 380mm outer diameter with a 32mm thickness and 54mm center bell height, delivering exceptional heat dissipation and consistent braking performance under extreme conditions.

Key Features:

• 380mm x 32mm rotor dimensions for increased thermal capacity
• 2-piece floating disc design reduces unsprung weight and thermal stress
• Type 3 (TY3) bell configuration for specific mounting applications
• 54mm center bell height (54a specification)
• Premium cast iron friction rings with Brembo's racing-grade metallurgy
• Directional vane design maximizes airflow and cooling efficiency
• Compatible with Brembo racing caliper systems

Brembo PISTA series rotors are designed for dedicated track use and professional motorsports applications where maximum braking performance is essential. The 2-piece construction allows the rotor to expand and contract independently from the aluminum bell, reducing brake fade and extending component life during sustained hard use.
