Brembo 4KC.8025A PISTA 4 TY5 2-Piece Rear Brake Discs 345x28mm

The Brembo 4KC.8025A PISTA 4 TY5 is a high-performance 2-piece rear brake disc system engineered for track and high-performance street applications. This premium disc features a 345mm outer diameter with a 28mm thickness and 54mm center bore, delivering exceptional braking performance and heat dissipation.

Key Features:

• 2-piece floating disc design reduces unsprung weight and allows for thermal expansion
• 345mm diameter x 28mm thickness for increased thermal capacity and bite
• 54mm center bore (Type 5 mounting) ensures precise fitment
• High-carbon cast iron friction ring for consistent performance and durability
• Aluminum bell hat reduces rotating mass for improved handling response
• Designed for rear axle installation on high-performance vehicles
• Track-proven PISTA series engineering from Brembo Racing heritage

Brembo's 2-piece disc construction separates the friction ring from the mounting bell, allowing each component to expand and contract independently under extreme thermal stress. This design minimizes disc warping, extends service life, and provides more consistent pedal feel during aggressive driving. The PISTA 4 series represents Brembo's commitment to delivering racing-level performance for dedicated enthusiasts and track day participants.
