Brembo 103.9040A 2-Piece Slotted Type-3 Brake Rotor Set

The Brembo 103.9040A is a 2-piece slotted brake rotor set from Brembo's performance disc upgrade line. Engineered as a direct OEM replacement, this system upgrades the heavy single-piece rotor to a lightweight 2-piece disc assembly without requiring modifications to the stock brake calipers.

Key Features:

• 2-Piece Construction: Features an outer cast iron braking surface paired with a lightweight aluminum bell/hat, reducing corner weight and improving overall vehicle dynamics
• Type-3 Slot Pattern: Extensively proven in professional motorsports, the Type-3 slot pattern delivers high initial brake response with excellent release characteristics and consistent disc wear
• Floating Disc Design: The disc-to-hat mounting uses floating H-bobbin hardware with anti-rattle springs, allowing thermal expansion without rotor distortion or cracking under high heat
• High Carbon Alloy Disc Material: Advanced high-carbon alloy iron with corrosion-resistant plating provides superior thermal capacity, shortened cooling times, and reduced vibration and noise
• OEM Integration: Designed to work seamlessly with OEM calipers and braking systems, ensuring proper safety and fitment right out of the box
• Reduced Thermal Deformation: Brembo's 2-piece floating design reduces permanent thermal deformation by up to 70% compared to conventional one-piece rotors
• Pre-Assembled: Comes as a complete axle set, pre-assembled with all necessary hardware included

The Brembo 103.9040A 2-piece disc system is the ideal upgrade for drivers seeking improved braking performance, reduced unsprung weight, and enhanced heat management on both the street and track.
