Upgrade your Honda Civic Type R’s braking system with GiroDisc’s high-performance 2-piece rotors and direct-fit replacement rings—designed to deliver unmatched stopping power, reduced unsprung weight, and consistent thermal performance whether you're daily driving, canyon carving, or pushing limits on the track.

Engineered specifically for the FK2, FK8, and FL5 Civic Type R platforms, GiroDisc rotors are precision-machined in the USA and built around a fully serviceable 2-piece floating design. The outer rings are crafted from GiroDisc’s proprietary high-carbon cast iron, known for its strength, thermal stability, and resistance to distortion under repeated high-heat cycles. The inner hats are CNC-machined from 6061-T6 aerospace-grade aluminum and anodized for long-term corrosion resistance. This combination allows GiroDisc rotors to significantly reduce unsprung and rotational mass compared to OEM units—improving suspension responsiveness, acceleration, and overall handling.

The floating mount design uses cadmium-plated steel drive pins and spring washers to allow the rotors to expand and contract freely under extreme heat, which minimizes stress, warping, and cracking. This also contributes to improved pedal feel, longer rotor life, and quieter operation under demanding conditions.

When your rotor rings are worn, there’s no need to purchase an entirely new rotor assembly. Simply swap in GiroDisc's direct-fit front (D1-047) or rear (D2-166) replacement rings using your existing GiroDisc hats. All replacement rings include new hardware for a complete and worry-free refresh of your braking system.

Unlike many factory or aftermarket 2-piece setups, GiroDisc components are designed to be modular, lightweight, and fully rebuildable—making them a cost-effective long-term upgrade for enthusiasts who demand performance without compromise.

Whether you’re looking to drop lap times, improve brake feel during aggressive driving, or simply extend the life of your braking components, GiroDisc rotors and replacement rings offer one of the best upgrades available for your Civic Type R.
