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.

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.
