Brembo 4K3.8023A PISTA Racing Brake Discs - 4 TY3 2-Piece 345x28mm Rear

The Brembo 4K3.8023A PISTA 4 TY3 is a high-performance 2-piece floating brake disc designed for track and racing applications. This rear brake disc features a 345mm outer diameter, 28mm thickness, and 54mm center bell mounting pattern, providing exceptional stopping power and heat dissipation for demanding motorsport use.

Key Features:

• 2-piece floating disc design reduces unsprung weight and allows thermal expansion
• 345mm diameter x 28mm thickness for maximum braking surface and heat capacity
• Type 3 (TY3) bell configuration with 54mm center bore
• Manufactured from high-carbon cast iron for superior thermal stability
• Directional curved vane design optimizes cooling airflow
• Precision ground friction surfaces ensure consistent pad contact
• Designed for rear axle applications in high-performance vehicles

Brembo's PISTA series represents their top-tier racing brake technology, engineered to withstand the extreme temperatures and stresses of competitive motorsport. The 2-piece design separates the friction ring from the aluminum bell, reducing weight while allowing independent thermal expansion to minimize disc warping and maintain consistent performance throughout extended track sessions.
