Girodisc Two-Piece Front Brake Rotors Compatible with C6 and C7 Corvette Including Z07 Performance Package

Description

The Girodisc Front Iron Rotor Conversion replaces fragile, expensive OEM carbon-ceramic (or stock) rotors with a high-performance 2-piece iron rotor setup built for real-world use — enhancing durability, brake cooling, and long-term serviceability. With a floating-hat design using a lightweight aluminum “hat” and replaceable cast-iron disc rings, this conversion delivers race-inspired braking performance, improved heat dissipation, and easier maintenance without altering brake bias or requiring caliper changes. It’s a smart upgrade for Corvette owners who want reliable, repeatable braking — whether for spirited street driving, track days, or long-term ownership.

Fitment Notes

• Compatible with Chevrolet Corvette C6 Z07 / ZR1 and C7 Z06 / Grand Sport / Z07-equipped models originally fitted with carbon-ceramic (CCM) or large-brake front rotors.

• Direct-bolt replacement — uses factory hubs and OEM calipers, no modifications required. 

• Requires use of brake pads with a pad-swept annulus (contact surface width) of 66 mm or less (e.g. FMSI-format 1405 pads) to ensure proper pad-to-rotor contact.

Included

• Pair of 2-piece front rotors (left and right) — each combining a 6061-T6 aircraft-grade aluminum hat with a cast-iron rotor ring.

• Floating-mount hardware: high-strength, cadmium-plated drive pins, hardened washers, and anti-noise spring washers to allow thermal expansion while suppressing cold-start rattles.

Product Specs

• Rotor design: Two-piece floating rotor with curved-vane internal cooling vanes — acts like a centrifugal pump to draw air through the disc for better cooling under repeated hard braking. 

• Materials: 6061-T6 aluminum hat; proprietary high-carbon cast-iron rotor rings, machined entirely in-house. 

• Maintenance: Rotor rings are replaceable — if worn or warped, only the rings need replacing, while the hats stay reusable, reducing long-term costs. 

• Brake pad compatibility: Requires performance or track-ready pads with ≤ 66 mm annulus (e.g. FMSI 1405 spec) — not compatible with stock-width pads sized for ceramic rotors.

Product Features

• True Floating Rotor Design — Floating hat + rotor arrangement ensures thermal expansion without warping or uneven stress — leading to more consistent braking and longer rotor life.

• Improved Cooling & Fade Resistance — Curved-vane cooling vanes force air through the rotor under braking load, improving heat dissipation — ideal for track days or repeated high-G braking.

• Lightweight Unsprung Mass — Aluminum hat reduces rotational and unsprung mass compared to one-piece steels or heavier stock rotors, which can slightly improve suspension response and overall handling feel.

• Serviceable & Cost-Effective — Once installed, only the iron rings wear — hats and hardware remain, making replacement quicker and cheaper than full rotor swaps.

• OEM-Caliper & ABS Compatible — Works with factory calipers and brake bias; no need for caliper upgrades or ABS rework, preserving vehicle electronics and brake balance.

• Reliable for Street, Track, or Dual Use — Offers the durability and repeatable performance needed for aggressive driving or track sessions, while keeping braking characteristics suitable for daily-driving use.
