Brembo 10C.9039A Two-Piece Replacement Brake Rotor Disc

The Brembo 10C.9039A is a two-piece replacement brake rotor disc designed for use with Brembo's Gran Turismo (GT) big brake kit systems. As a direct replacement rotor ring, it is engineered to restore full braking performance to an existing Brembo GT two-piece brake system without the need to replace the entire assembly.

Key Features:

• Two-Piece Construction: Separates the iron braking surface from the aluminum hat, reducing unsprung weight by up to 30% compared to a conventional one-piece rotor of the same size
• High Carbon Cast Iron: The braking surface is manufactured from high carbon cast iron alloy for optimal thermal conductivity, minimized noise, and reduced vibration
• Floating Design: The disc-to-hat mounting system uses floating hardware (D-bobbins) that allows the iron ring to expand freely under thermal stress, reducing permanent thermal deformation by up to 70% versus solid rotors
• Brembo GT System Compatible: Engineered as a direct replacement component for Brembo GT two-piece brake kit systems, maintaining OEM-grade fit, form, and function
• Performance-Proven: Brembo two-piece rotor technology is derived directly from motorsport applications, including GT3 and endurance racing programs
• Corrosion Protection: Features Brembo's UV-cured coating for superior corrosion resistance without harmful solvents, ready to install straight from the box

Replacing worn rotor rings on a two-piece system is a cost-effective way to maintain peak braking performance while retaining the existing aluminum hat. The Brembo 10C.9039A is manufactured to Brembo's stringent tolerances and quality standards, delivering confidence-inspiring stopping power on the street or track.
