GiroDisc A2-147 2-Piece Slotted/Vented Rear Rotors for 14-19 Chevrolet Corvette

Vehicle Fitment

• 2014-2019 Chevrolet Corvette C7 Z06 (with factory iron rear rotors)
• 2014-2019 Chevrolet Corvette C7 Grand Sport (with factory iron rear rotors)

Features

• 2-piece floating rotor design - 6061-T6 aluminum hat + high-carbon cast-iron disc ring to reduce unsprung and rotating mass
• Slotted & vented disc surface with curved-vane internal ventilation - improves cooling and helps evacuate pad gas, dust, and debris under heavy braking
• Floating-mount assembly with high-strength steel drive pins, Belleville washers, and spring clips - allows thermal expansion and self-centering without noise
• Direct bolt-on replacement - fits OEM rear hubs and calipers, no modification required
• Reusable hat design - when rotor rings wear out, only the rings need replacement instead of the full rotor assembly
• Reduces unsprung and rotational mass compared to stock - enhances suspension response, braking modulation, and overall handling dynamics
• Better brake cooling and fade resistance compared to stock rotors - ideal for spirited driving or occasional track use
• Made in USA from domestic materials - machined aluminum hats and proprietary cast-iron rings for durable, race-grade rotor construction

Product Description

The GiroDisc A2-147 rear rotor set is a high-performance upgrade designed specifically for 2014-2019 Chevrolet Corvette C7 Z06 and Grand Sport models equipped with factory iron rear rotors. By replacing the stock one-piece rotors with a floating 2-piece design - featuring a lightweight aluminum hat and a machined cast-iron rotor ring - A2-147 reduces unsprung and rotating mass. This weight reduction enhances rear suspension responsiveness, improves braking modulation, and contributes to better overall handling, especially under aggressive driving or repeated braking events.

Thanks to the slotted and vented disc surface alongside GiroDisc's curved-vane internal ventilation, A2-147 delivers improved cooling efficiency and better evacuation of pad gases, dust, and debris - which helps reduce brake fade and maintain stable stopping power during spirited driving or track sessions. The floating-mount design allows for thermal expansion and self-centering, while the included hardware eliminates common floating-rotor issues such as vibration or cold-start rattle. And because the rotor ring is replaceable, long-term maintenance is simplified and more cost-effective: when rings wear or reach minimum thickness, you only replace the rings - reusing the aluminum hats. For Corvette C7 owners seeking a robust, durable, and performance-ready rear braking upgrade without changing calipers or altering brake bias, GiroDisc A2-147 is a well-balanced, direct-fit solution.
