Honda Civic Type R FK2, FK8, FL5 Front Rotors (Girodisc A1-166)
The Girodisc Front Rotor set for the Honda Civic Type R delivers a precision-engineered braking upgrade that maintains OEM fitment while enhancing performance and durability. Designed as a direct replacement for the factory rotors, these lightweight two-piece rotors improve response, heat management, and braking consistency on both street and track applications.
Vehicle Fitment
This Girodisc front rotor set fits the following models:
- Honda Civic Type R FK2 (2015–2017)
- Honda Civic Type R FK8 (2017–2021)
- Honda Civic Type R FL5 (2023–present)
Compatible with OEM calipers and factory brake systems. Direct bolt-on installation with no modifications required.
Performance and Design
Each Girodisc rotor weighs approximately 21.1 lbs compared to 24.6 lbs for the factory rotor, resulting in a substantial reduction of rotational and unsprung mass. The central hat is CNC-machined from U.S.-sourced 6061-T6 aircraft-grade aluminum, while the friction ring is made from Girodisc’s proprietary cast iron. The curved vane internal structure acts as a centrifugal pump to draw cooling air through the disc, enhancing thermal control under sustained braking.
Features
- Direct OEM replacement; bolts on with no modifications required.
- Two-piece floating rotor design improves response and reduces unsprung weight.
- Proprietary cast iron friction ring paired with a 6061-T6 aluminum hat for strength and heat resistance.
- Curved vane internal design promotes cooling and fade resistance under aggressive driving.
- Floating mount system with ten high-strength alloy steel drive pins allows for controlled axial and radial float.
- Anti-noise spring washers eliminate rattle during cold or street use while maintaining full float when hot.
- Cadmium-plated hardware resists corrosion for long-term durability.
- Designed, cast, and machined entirely in the USA to Girodisc’s motorsport standards.

FAQs: Honda Civic Type R FK2, FK8, FL5 Front Rotors (Girodisc A1-166)
Do these rotors require aftermarket calipers? No, they are designed to work perfectly with the OEM Brembo calipers found on all Type R models listed.
What are the performance benefits over stock? Reduced weight, improved cooling efficiency, and consistent pedal feel under repeated heavy braking.
Are these rotors noisy during everyday driving? No. The spring-washer design prevents rattle and vibration during street use while maintaining the benefits of a floating system under heat.
Can these be serviced? Yes. When the cast iron rings wear out, they can be replaced individually while reusing the aluminum hats and hardware.
