GiroDisc Front Replacement Rings – Porsche 991.2 GT2 RS Clubsport

Replace worn front brake rotor rings on your Porsche 911 GT2 RS Clubsport (991.2) with GiroDisc D1-250 slotted replacement friction rings.

Designed for vehicles equipped with the GiroDisc A1-250 front rotor assemblies, these 390mm cast-iron replacement rings allow you to retain your existing GiroDisc aluminum center hats rather than purchasing complete new rotors.

The replacement rings are supplied as a left and right pair, with new mounting hardware included.

Rotor Diameter: 390mm
Application: Porsche 991.2 GT2 RS Clubsport
Sold as a pair – left and right front rings

Designed for GiroDisc Front Rotor Assemblies

The D1-250 replacement rings are designed specifically for the GiroDisc A1-250 front brake rotor system used on the Porsche GT2 RS Clubsport.

The two-piece GiroDisc system separates the cast-iron friction ring from the aluminum center hat, allowing the wear component to be replaced independently.

When the friction rings reach their service limit, the original GiroDisc hats can be reused provided they remain in serviceable condition.

390mm Slotted Racing Friction Rings

GiroDisc replacement rings feature a proprietary cast-iron construction developed for high-performance braking applications.

The slotted friction surface is designed for demanding track and competition use, helping maintain a consistent interface between the brake pads and rotor during repeated braking cycles.

Internal cooling vanes promote airflow through the rotor to help manage temperatures during heavy braking.

Replace the Rings – Keep the Hats

One of the primary advantages of the GiroDisc two-piece rotor system is reduced long-term replacement cost.

Rather than replacing complete rotor assemblies every time the friction rings wear out, customers can replace only the cast-iron rings while retaining the aluminum hats.

This makes the D1-250 a practical service component for race teams maintaining GT2 RS Clubsport brake systems.

Replacement Hardware Included

Each pair of GiroDisc D1-250 replacement rings includes the mounting hardware required to attach the new rings to compatible existing GiroDisc hats.

The existing aluminum hats are reused, provided they pass inspection.

Important – GiroDisc Hats Only

D1-250 replacement rings are designed for GiroDisc aluminum rotor hats.

They are not intended for factory Porsche rotor hats or other manufacturers’ two-piece rotor assemblies.

If your GT2 RS Clubsport still has its original factory rotor assemblies, you will need the appropriate complete GiroDisc rotor system before using these replacement rings.

Important Fitment Note

These are replacement friction rings only, not complete brake rotor assemblies.

The GiroDisc D1-250 requires compatible GiroDisc front rotor hats. Factory Porsche rotor hats and hats from other manufacturers are not compatible unless specifically approved by GiroDisc.

Inspect the existing hats before reuse and follow GiroDisc’s assembly and installation instructions.

If you need complete front rotors, select the GiroDisc A1-250 front rotor assemblies instead.
