The GiroDisc A1-319 2-piece front rotors upgrade transforms the stock iron rotors on a C8 Z06 into a lighter, cooler, and more track-ready braking setup — shedding unsprung and rotating mass while improving cooling under heavy braking. Made with a high-carbon iron rotor ring and lightweight aluminum hat, these rotors deliver consistent, fade-resistant braking performance whether you’re hitting the track, canyon roads, or simply pushing the car hard on the street.
Designed specifically for Corvette C8 Z06 models equipped with the standard iron front brake setup — not compatible with the Z07 carbon-ceramic brake package.
Direct bolt-on replacement — mounts to factory hubs and uses OEM calipers, with no modifications or caliper swaps required.
Sold as a pair (left + right rotors).
Two (2) 2-piece floating front brake rotors (left and right) consisting of:
6061-T6 aluminum “hat” (anodized finish) for lightweight mounting.
Proprietary high-carbon cast-iron rotor rings, machined in-house to GiroDisc specifications.
Floating-mount hardware: high-strength alloy steel drive pins (cadmium-plated), hardened washers, and anti-noise spring washers — allowing thermal expansion and preventing noise when cold.
Rotor type: 2-piece floating rotor (aluminum hat + iron rotor ring) with ventilated, curved-vane internal cooling design.
Cooling design: 72 curved internal vanes that act like a centrifugal pump — pulling air through the hub to cool the rotor under heavy braking and mitigate fade.
Minimum service thickness (rotor ring): replace when ring thickness reaches 32 mm (or sooner if cracks propagate to the edge).
Reduced Unsprung & Rotational Mass — Floating-hat aluminum design helps lower unsprung weight and inertia, improving suspension response and brake modulation.
Enhanced Cooling & Fade Resistance — Curved internal vanes draw cooling air through the rotor under repeated heavy braking, keeping temperatures down and pedal feel more consistent.
Bolt-On OEM Compatibility — No need to change calipers or hubs; the rotors bolt directly onto stock mounting points and work with OEM brake hardware and ABS/bias settings.
Replaceable Rotor Rings for Long-Term Value — When the rotor ring wears or gets damaged, only the ring needs replacement — reuse the hat assembly, saving cost over a full rotor swap.
Balanced for Street & Track Use — Designed to handle both high-performance street driving and track-day demands, offering improved braking performance without sacrificing everyday usability.
