Brembo 4KC.9006A PISTA 6-Piston Rear Brake Disc 380x32mm 2-Piece

The Brembo 4KC.9006A represents a professional-grade rear brake disc assembly from the acclaimed PISTA racing series, engineered for extreme track conditions and competitive motorsports. This 2-piece disc system combines a 380mm diameter by 32mm thick high-carbon rotor with an aluminum hat assembly, delivering enhanced thermal management and reduced unsprung weight for improved vehicle dynamics.

Key Features:

• 380mm x 32mm x 53mm mounting configuration for rear axle applications
• TY5 "Endurance" slot pattern optimized for extended track sessions and maximum disc longevity
• 2-piece floating disc construction with aluminum hat reduces rotational mass while maintaining rigidity
• High-thermal capacity design with narrow air-gap construction for superior heat dissipation
• Advanced vented rotor design efficiently evacuates heat and brake gases
• Compatible with PISTA 6-piston racing calipers for professional-level stopping power
• Corrosion-resistant plating extends service life in demanding environments

Designed for track day enthusiasts and racing applications, this disc assembly delivers consistent performance under extreme braking loads. The TY5 slot pattern provides excellent initial bite with smooth pad release characteristics, making it ideal for endurance racing and high-frequency track use where disc durability is paramount. The floating bobbin mounting system allows controlled thermal expansion while anti-rattle springs minimize noise during street driving.
