GiroDisc A2-271 2-Piece Slotted Rear Rotors for 2016-2025 Chevrolet Camaro SS

Vehicle Fitment

• 2016-2025 Chevrolet Camaro SS (6th Generation, rear axle, 1LE and other trims with compatible OEM rear calipers)

Features

• 2-piece floating rotor design - 6061-T6 aluminum hat + high-carbon cast-iron rotor ring to reduce unsprung and rotational mass
• Slotted and vented disc surface for improved pad bite, efficient gas/debris purge, and enhanced braking performance under heavy use
• Curved-vane internal ventilation - acts as a centrifugal pump to pull cooling air through the rotor during repeated braking, improving heat dissipation and fade resistance
• Floating-mount system using high-strength alloy steel drive pins, hardened cap screws, and anti-noise spring washers - allows thermal expansion, self-centering and quiet operation (no cold-start rattle)
• Direct bolt-on replacement - fits OEM rear calipers and hub assembly without modification, preserving factory brake bias and ABS function
• Reduced unsprung & rotating mass improves suspension response, acceleration, and braking modulation compared to stock rotors
• Re-useable hat design - when rotor rings wear out, only the cast-iron rings need replacement, reducing long-term maintenance cost
• Race-grade construction and workmanship - built to handle street driving, spirited runs, or occasional track use

Product Description

The GiroDisc A2-271 rear rotor set is a performance-focused upgrade engineered specifically for the 2016-on 6th-generation Chevrolet Camaro SS. By replacing the heavier stock rear discs with a floating 2-piece rotor - combining a lightweight aluminum hat and a high-carbon cast-iron rotor ring - A2-271 reduces unsprung and rotational mass. This weight reduction improves suspension responsiveness, braking modulation, and rear-end stability under braking, while preserving OEM brake geometry and ABS calibration.

With its slotted and vented disc surface, plus curved-vane internal ventilation, A2-271 delivers superior cooling and effective pad-gas/debris purge, helping to maintain consistent braking performance under repeated use, spirited driving, or occasional track sessions. The floating-mount hardware ensures that the rotor can expand under heat while self-centering, all without introducing cold-start rattle or vibration. Long-term maintenance is also more convenient and cost-effective: when the iron rotor rings wear or reach service limit, they can be replaced without needing to replace the aluminum hats. For Camaro SS owners looking for a durable, upgrade-ready rear braking solution with improved performance and reduced weight - A2-271 is a strong, direct-fit choice.
