Brembo 4K3.9007A PISTA 4 TY3 Rear 2-Piece Brake Discs 380x28mm

The Brembo 4K3.9007A PISTA 4 TY3 is a high-performance 2-piece rear brake disc system engineered for serious track and racing applications. These premium discs feature a 380mm diameter with a 28mm thickness, providing exceptional thermal capacity and fade resistance under extreme braking conditions.

Key Features:

• 2-piece floating disc design reduces unsprung weight and allows for thermal expansion
• 380mm (approximately 15 inch) outer diameter for increased braking surface area
• 28mm disc thickness provides substantial thermal mass for heat dissipation
• 54mm center bell dimension (54a specification) for precise fitment
• Type 3 (TY3) design optimized for rear axle applications
• PISTA series construction designed specifically for track and racing use
• Manufactured to Brembo's exacting motorsport standards

The 2-piece design separates the friction ring from the aluminum bell, reducing rotating mass while maintaining structural integrity. This configuration also allows the disc to expand and contract with temperature changes without warping, ensuring consistent performance lap after lap. Ideal for high-performance vehicles requiring upgraded braking capacity for track day, time attack, or professional racing applications.
