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.

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.
