Brembo 103.9038A 2-Piece Brake Rotor Disc Upgrade Kit Slotted Type-3

The Brembo 103.9038A is a high-performance two-piece brake rotor disc from Brembo's industry-leading lineup of OEM-integrated disc upgrades. Engineered for drivers who demand maximum braking performance on both the street and track, this rotor features a two-piece floating disc construction comprised of an outer iron disc ring paired with a lightweight aluminum bell/hat, delivering significant reductions in unsprung corner weight for improved handling, acceleration, and braking response.

Key Features:

• Two-Piece Floating Construction: Aluminum hat/bell combined with an advanced high-carbon alloy iron disc ring reduces weight compared to traditional one-piece rotors
• Type-3 Slot Pattern: Extensively proven in professional motorsport, the Type-3 slot design provides aggressive initial brake bite, consistent pad surface refreshing, and excellent release characteristics
• Floating D-Bobbin Hardware: Anti-rattle spring bobbins allow the outer disc to float relative to the bell, dramatically reducing permanent thermal deformation and managing heat-induced stress
• Advanced High-Carbon Alloy Material: Superior thermal capacity and heat dissipation compared to standard cast iron, with corrosion-resistant plating for long-term durability
• OEM Integration: Designed to work seamlessly with OEM calipers and braking systems, ensuring maximum safety and direct-fit installation
• Reduced Brake Fade: Enhanced ventilation and high thermal capacity minimize brake fade under repeated hard stops and extended track use
• Sold as a Complete Axle Set: Comes pre-assembled with all necessary mounting hardware included

Brembo's two-piece rotor technology delivers a measurable reduction in permanent thermal deformation versus conventional one-piece disc designs, along with reduced residual torque and vibrations. Whether used for spirited street driving or demanding track events, the Brembo 103.9038A is a proven upgrade for drivers seeking OEM-quality engineering with enhanced performance characteristics.
