Girodisc Chevrolet Camaro Z/28 (5th Gen) Rear Iron Rotor Conversion Upgrade your 5th-Gen Camaro Z/28 with Girodisc’s rear iron rotor conversion, engineered as a direct replacement for the OEM carbon-ceramic rotors. This high-performance setup delivers superior heat control, lower replacement costs, and the same confident braking feel that made the Z/28 a track legend. Direct Carbon-Ceramic Replacement, Built to Perform The Girodisc system is a true bolt-on solution—no modifications or adapters needed. Each rotor features a CNC-machined 6061-T6 aluminum hat mated to Girodisc’s proprietary cast-iron friction rings, both made in the USA. The floating two-piece design manages heat expansion under hard braking, maintaining perfect pad contact and preventing warping. Curved internal vanes act like centrifugal pumps to pull cooling air through the discs, keeping temperatures in check lap after lap. Features • Direct replacement for OEM carbon-ceramic rear rotors• Billet 6061-T6 aluminum hats with hard-anodized finish• Proprietary cast-iron rings poured and machined in the USA• Floating mount system with cadmium-plated steel drive pins• Anti-noise spring washers eliminate rattle while allowing float• Curved vane design improves airflow and cooling• Fully rebuildable—replace only the rotor rings when worn• Sold/priced per pair Vehicle Fitment Chevrolet Camaro Z/28 (2014–2015, 5th Generation)Fits OEM carbon-ceramic brake systems with factory Brembo calipers. Girodisc A2-172 Rear Rotor FAQs: Why switch from carbon-ceramic to iron rotors? Iron rotors offer greater heat capacity, improved modulation, and dramatically reduced replacement cost—ideal for track-day or endurance use where carbon ceramics can degrade quickly. Are these a direct fit for the Z/28’s carbon-ceramic setup? Yes. They bolt directly to the factory hubs and work with the original Brembo calipers and parking-brake system. Do these affect ABS or stability control? No. Girodisc rotors maintain factory geometry and tone-ring compatibility, so all electronic systems function normally. What difference will I feel when driving? Expect smoother pedal feedback, improved heat management under repeated hard braking, and more consistent stopping power throughout a session. Upgrade your Camaro Z/28 with Girodisc’s rear iron rotor conversion and experience the durability, balance, and braking precision trusted by serious track drivers everywhere.

Chevrolet Camaro Z/28 (5th Gen) Front Iron Rotor Conversion The Girodisc Front Iron Rotor Conversion for the fifth-generation Chevrolet Camaro Z/28 provides a lightweight, high-performance alternative to the factory carbon-ceramic rotors. Designed as a direct replacement for the OE discs, this system bolts on with no permanent modifications required. For optimal performance and reasonable rotor weight, it requires brake pads with a swept area (annulus) of 66mm or less, using the FMSI #1405 pad shape. Performance and Design By switching from carbon-ceramic to iron rotors, drivers benefit from improved heat management, reduced replacement costs, and consistent braking performance under repeated heavy use. The Girodisc design maintains factory brake bias and ABS functionality while significantly improving serviceability. Features - Direct replacement for the OEM front carbon-ceramic rotors. - Requires the FMSI #1405 pad shape (available in multiple compounds). - Two-piece floating rotor assembly combines a proprietary cast iron friction ring with a precision-machined 6061-T6 aluminum hat. - Curved internal vanes act as a centrifugal pump to maximize cooling airflow through the rotor. - Floating mount system with 12 high-strength alloy steel drive pins allows axial and radial float to accommodate heat expansion and reduce stress. - Anti-noise spring washers eliminate the rattle typically associated with floating rotors during street use. - Cadmium-plated hardware ensures long-term corrosion resistance and durability. - Lightweight two-piece design lowers rotational and unsprung mass, improving acceleration, steering response, and suspension control. Specifications Rotor Type: Two-piece floatingMaterial: Proprietary cast iron with 6061-T6 aluminum hatPad Requirement: FMSI #1405 (66mm swept area or less)Mount Hardware: 12 high-strength alloy steel drive pins, class 12.9 cap screwsOrigin: Designed, cast, and machined in the USAFitment: Chevrolet Camaro Z/28 (5th Gen) FAQs: Chevrolet Camaro Z/28 (5th Gen) Front Iron Rotor Conversion Why do I need to use a different pad shape? The Girodisc rotors are optimized for a 66mm pad annulus to maintain ideal weight and thermal characteristics. The required pad shape is FMSI #1405. Can I reuse my OEM pads? No. The OEM pads are too large for the reduced swept area and may cause overheating or excessive wear. Will this affect my ABS or brake balance? No. The system retains the factory brake bias and integrates seamlessly with the stock calipers and ABS tuning. Are these rotors noisy? The use of spring washers in the floating mount design minimizes rattle and vibration while still allowing full float under thermal load. What happens when the rotors wear out? The aluminum hats are reusable; you only need to replace the cast iron friction rings and reassemble with new hardware. Ordering Information Sold and priced per pair. Includes left and right front Girodisc rotors for the Chevrolet Camaro Z/28 (5th Gen). Requires FMSI #1405 brake pads for installation.

Corvette C6 ZR1, C7 (Z07 CCM) Front Iron Rotor Conversion The Girodisc Front Iron Rotor Conversion provides a direct, lightweight, and track-ready replacement for the OEM carbon ceramic rotors found on the Corvette C6 ZR1 and C7 Z06/Z07 with the carbon brake package. Designed to bolt directly to the car with no modifications, these rotors maintain OEM brake bias, ABS calibration, and pedal feel while offering greater durability and cost-effective serviceability. To optimize performance and keep overall weight in check, this system requires brake pads with a swept area (annulus) of 66mm or less. Girodisc recommends the FMSI 1405 pad shape, which is widely used across performance applications and available in multiple compounds to suit your driving needs. These rotors deliver consistent, fade-free braking performance under the most demanding conditions, from street use to full race duty. Precision-Engineered Performance Vehicle Fitment Chevrolet Corvette C6 ZR1 Chevrolet Corvette C7 Z06 / Z07 Package (CCM Brakes) Features Direct CCM-to-iron conversion: Replaces OEM carbon ceramic rotors with precision-engineered iron rotors that bolt directly to the factory calipers. Lightweight design: Maintains low rotational mass while improving heat dissipation and long-term durability. Curved vane cooling: Directional vanes act as centrifugal pumps to channel air through the rotors, reducing fade during sustained hard braking. Floating mount system: Twelve cadmium-plated drive pins and spring washers allow for thermal expansion while eliminating unwanted noise or vibration. Serviceable construction: Replaceable iron rings and reusable aluminum hats for long-term value and lower running costs. U.S.-made quality: Machined from domestic 6061-T6 aluminum and proprietary cast iron entirely in-house at Girodisc’s Washington facility. Girodisc A1-145 FAQs Do these replace OEM carbon ceramic rotors? Yes. They are designed as a direct bolt-on conversion for ZR1 and Z07 CCM systems. What brake pads should I use? Use a pad with a 66mm annulus or less—FMSI 1405 shape is recommended and available in multiple compounds. Will my brake bias or ABS be affected? No. Girodisc ensures full compatibility with OEM brake balance and electronic control systems. Are they quieter than CCM brakes? Yes, the anti-noise washers eliminate rattle while retaining full floating function. How are they sold? Rotors are sold and priced per pair.
