Brembo 4KC.8032A PISTA 4 TY5 2-Piece Rear Brake Discs 345x28mm

The Brembo 4KC.8032A PISTA high-performance brake disc system delivers race-proven stopping power for track and competition use. This rear axle kit features 345mm diameter, 28mm thick 2-piece floating rotors engineered to provide exceptional heat management and consistent braking performance under extreme conditions.

Key Features:

• 345mm x 28mm 2-piece floating disc design for superior heat dissipation
• TY5 bell configuration with 54mm center bore (54a mounting pattern)
• High-carbon cast iron friction ring for consistent friction coefficient
• Aluminum hat reduces unsprung weight while maintaining rigidity
• Floating design accommodates thermal expansion and reduces stress
• Track-focused PISTA series engineering for racing applications
• Rear axle application optimized for balanced brake bias

Brembo's PISTA 2-piece disc systems are designed for motorsport applications where weight savings, thermal performance, and reliability are critical. The floating rotor design allows independent expansion of the friction ring and aluminum bell, reducing distortion and maintaining flat friction surfaces even during prolonged high-temperature use. Each disc is precision-machined to strict tolerances for optimal pad contact and consistent pedal feel.
