Brembo 4K3.8029A PISTA 4 TY3 2-Piece Rear Brake Rotors 345x28mm

The Brembo 4K3.8029A PISTA 4 TY3 rear brake disc set delivers professional-grade stopping power for high-performance track and racing applications. These 2-piece floating rotors feature a 345mm outer diameter with a 28mm thickness and 54mm center bore, engineered to handle extreme thermal loads while maintaining consistent pedal feel lap after lap.

Key Features:

• 2-piece floating design reduces unsprung weight and allows for thermal expansion
• 345mm diameter x 28mm thick rotor dimensions for maximum heat capacity
• 54mm center bore for precise hub fitment
• Cast iron rotor rings with directional vane design for optimal cooling
• Aluminum center hat reduces rotational mass for improved suspension response
• TY3 configuration specifically designed for rear axle applications
• Brembo PISTA series engineering for track and competition use

Brembo's 2-piece rotor design separates the friction ring from the mounting hat, allowing each component to expand and contract independently under extreme temperatures. This prevents warping and cracking while maintaining flat, true rotor surfaces for consistent braking performance. The PISTA 4 TY3 rotors are manufactured to Brembo's racing standards and are ideal for dedicated track cars, time attack vehicles, and professional motorsports applications.
