Brembo 3K3.9031A PISTA 4 TY3 2-Piece Front Brake Rotors 380x34mm

The Brembo 3K3.9031A PISTA 4 TY3 represents the pinnacle of high-performance braking technology, designed for serious track enthusiasts and motorsport applications. This 2-piece floating rotor design features a 380mm diameter with a 34mm thickness, engineered to deliver exceptional stopping power and heat dissipation under extreme conditions.

Key Features:

• 2-piece floating disc design reduces unsprung weight while improving thermal management
• 380mm x 34mm rotor dimensions provide massive swept area for maximum braking performance
• 65mm center bell mounting pattern (TY3 configuration) for precise fitment
• Manufactured from premium cast iron alloy with optimized metallurgy for track durability
• Directional vane design enhances cooling efficiency during aggressive driving
• Front axle application for maximum deceleration capability
• Compatible with Brembo PISTA 4-piston calipers and racing brake systems

The PISTA (Italian for "track") series represents Brembo's dedicated racing technology, featuring two-piece construction that allows the rotor face to expand independently from the aluminum hat during thermal cycling. This design minimizes distortion, reduces judder, and maintains consistent brake pedal feel even during extended track sessions. The 34mm thickness provides substantial thermal mass to resist fade while the curved directional vanes maximize airflow for rapid heat dissipation.

Sold as a pair for front axle installation. Professional installation and proper bedding procedures are strongly recommended to achieve optimal performance and rotor longevity.
