The Girodisc two-piece front-rotor conversion for the C7 Corvette Z06 / Grand Sport replaces the factory discs with lightweight, performance-oriented 6061-T6 aluminum-hat + cast-iron rotor rings — delivering cooler, more consistent braking under heavy use and reducing unsprung/rotating mass for improved throttle response and suspension feel. Designed as a direct bolt-on replacement, this rotor set maintains OEM caliper compatibility and brake bias, while giving the braking system greater thermal stability and easier maintenance — ideal for track-day use, spirited driving, or high-performance street applications.
Compatible with Corvette C7 Grand Sport / Z06 (2014–2019) front-brake setups (non-carbon-ceramic / standard iron-rotor models).
Direct replacement: bolts to factory hubs and works with OEM (or equivalent) calipers — no modifications or caliper swaps needed.
Use of compatible brake pads is recommended (standard pad shapes matching the pad-swept area). The rotor design retains stock brake bias and ABS behavior.
Pair (left & right) of 2-piece floating rotors: 6061-T6 aluminum hats + proprietary cast-iron rotor rings machined in-house.
Floating-mount hardware: high-strength alloy steel drive pins, hardened washers, and spring washers to allow thermal expansion while minimizing noise.
Rotor material: 6061-T6 aircraft-grade aluminum hat; proprietary high-carbon cast-iron rotor ring, cast and machined in the USA.
Cooling design: Curved-vane, ventilated disc design that acts like a centrifugal pump — forcing airflow through the rotor under braking to improve heat dissipation and reduce fade.
Weight savings: Approximately 1.6 lbs per rotor lighter than stock (stock ~23.6 lb vs. ~22.0 lb).
Configuration: Floating-hat rotor with full floating mount system — accommodates thermal expansion and helps maintain pad-to-rotor alignment under stress.
Reduced Unsprung & Rotating Mass — Lighter rotor hat + ring reduces overall mass, which can improve suspension response, steering feel, and throttle response under acceleration or corner exit.
Improved Cooling & Fade Resistance — Curved-vane internal ventilation actively draws air through the rotor, helping maintain lower disc temperatures under repeated braking — ideal for track use or spirited driving.
Floating-Rotor Construction — The hat-and-ring design absorbs thermal expansion and maintains rotor alignment under high heat/stress, improving longevity and consistency.
Direct Fit / OEM Brake Compatibility — Designed to bolt directly to stock hubs and accept OEM calipers, preserving brake balance and ABS/traction control systems — no need for caliper upgrades.
Easier, Cost-Effective Maintenance — When the disc rings wear or warp, only the iron rings need replacing — hats and hardware can be reused — saving money long term vs one-piece rotors.
Balanced for Street & Track Use — Delivers performance-grade braking and cooling without requiring radical setup changes — a versatile solution whether you track the car or daily-drive it hard.
