Girodisc Front Iron Brake Rotor Conversion Kit for 2023+ C8 Corvette Z06 and E-Ray

Description

FThe GiroDisc A1-320 Front Iron Rotor Conversion replaces the OEM carbon-ceramic front rotors on a C8 E-Ray / Z06 with Z07 package with durable, high-performance two-piece iron rotors. By swapping to cast-iron rings and aluminum hats, this kit gives you better thermal stability under repeated heavy braking, improved cooling via internal vanes, and easier long-term maintenance (you only replace the rings, not the entire rotor). For track days, spirited driving or frequent braking stress, the conversion delivers predictable, fade-resistant performance while retaining compatibility with factory calipers.

Fitment Notes

• Fits C8 Corvette E-Ray / Z06 w/Z07 carbon-ceramic front brakes

• Direct bolt-on swap — uses factory hubs and calipers, no caliper upgrade or special adaptation required. 

• Requires switching to appropriate brake pads with pad-shape “D1405” (same as standard iron-brake Z06), since pad contact geometry differs from OEM ceramic-rotor pads.

Included

• Pair of front 2-piece floating rotors (left + right): each with a 6061-T6 aluminum hat and proprietary high-carbon cast-iron rotor ring.

• Floating-mount hardware: cadmium-plated drive pins, spring clips, Belleville washers and hardened washers — engineered to allow thermal expansion and maintain quiet operation on the street.

Product Specs

• Rotor Type: 2-piece floating rotor — aluminum hat + cast-iron ring.

• Cooling Design: Internal 72-curved-vane ventilation, which acts like a centrifugal pump to draw cooling air through the hub and rotor under heavy braking, reducing fade and heat buildup.

• Serviceability: Rotor rings replaceable — when ring thickness reaches minimum spec (34 mm) or if cracking occurs, you can replace just the ring (part number D1-320), reusing the aluminum hats.

• Compatibility: Works with factory front Brembo Z07 calipers using pad-shape D1405 (same as standard Z06 iron-brake variant).

Product Features

• High-Temperature Stability & Fade Resistance — The cast-iron disc rings and strong metallurgy resist thermal stress better than ceramic in repeated heavy braking, keeping brake performance consistent. 

• Improved Cooling Under Load — The internal curved-vane ventilation design pulls ambient air through the rotor during braking, lowering rotor temperature, minimizing brake fade — beneficial for track sessions or spirited driving. 

• Reduced Cost of Consumables — When rings wear out, only the inexpensive iron rings need replacement; the aluminum hats remain reusable — a more economical solution over time.

• Full OEM Caliper & Hub Compatibility — No need to change calipers or adapt hardware: rotors bolt straight onto factory hubs and accept OEM Z07 calipers with proper pads.

• Better Brake Modulation & Predictability — Floating rotor design accommodates thermal expansion and maintains pad-to-rotor alignment — giving more consistent pedal feel and braking behavior during both street and track use. 

• Track-Ready Durability with Street Usability — Built to withstand repeated heavy use and high heat cycles but engineered to remain quiet and street-friendly when cooled — balancing performance with daily usability.
