Brembo 20C.6001A GT Series 328x28mm 2-Piece Cross-Drilled Rear Brake Rotor Upgrade Kit

The Brembo 20C.6001A is a GT Series rear brake rotor upgrade kit featuring a 328mm x 28mm 2-piece floating disc design. This complete axle set arrives pre-assembled with all necessary hardware included, providing a direct OEM replacement upgrade for high-performance applications.

2-Piece Floating Disc Construction:

• Disc diameter: 328mm (12.9")
• Disc width (thickness): 28mm
• Disc type: Cross-Drilled
• Vane design: Vented curved 48-vane configuration
• Disc material: Advanced high-carbon alloy with corrosion-resistant plating
• Hat-to-disc mounting: Floating D-Bobbin with anti-rattle spring
• Position: Rear axle set

Key Features:

• Two-piece floating disc design allows the iron braking surface and aluminum hat to expand independently under thermal stress, preventing warping and heat-induced cracking
• Lightweight aluminum hat reduces unsprung rotational mass for improved handling, acceleration response, and braking feel
• Cross-drilled holes help expel heat and gases more effectively, delivering excellent bite on wet and slippery surfaces
• Advanced high-carbon alloy iron provides superior resistance to heat fade compared to standard cast iron
• Corrosion-resistant plating finish protects non-swept rotor surfaces
• Designed to meet OE specifications for a seamless, no-modification installation
• Complete axle set — both left and right rotors (disc and bell pre-assembled) and all necessary hardware included

Engineered for performance street and track use, the Brembo 20C.6001A 2-piece brake rotor upgrade kit delivers measurable improvements in thermal capacity, stopping power, and braking consistency over stock rotors — all while reducing corner weight for sharper vehicle dynamics.
