GiroDisc Front Replacement Rings – Porsche 991 GT3 Cup & GT4 Clubsport – 380x32mm

Description

GiroDisc Front Replacement Rings – Porsche 991 GT3 Cup & GT4 Clubsport

Replacement slotted rotor rings for GiroDisc front brake rotor assemblies on the Porsche 991 GT3 Cup and Porsche GT4 Clubsport.

These rings allow you to rebuild your existing GiroDisc front rotor assemblies while reusing the aluminum center hats. Once the friction rings reach their service limit, there is no need to purchase another complete rotor assembly as long as the existing GiroDisc hats remain serviceable.

GiroDisc Part Number: D1-238
Rotor Size: 380mm × 32mm
Sold as a pair.
Replacement hardware included.

Applications

• Porsche 991 GT3 Cup
• Porsche GT4 Clubsport equipped with compatible GiroDisc front rotor assemblies

Important – For GiroDisc Hats

These D1-238 replacement rings are designed specifically for GiroDisc rotor hats.

They are not intended for factory Porsche/PFC rotor hats or hats from other manufacturers.

If your car still uses the factory Porsche/PFC two-piece rotor system, a different GiroDisc replacement ring is required.

Keep the Hats – Replace the Wear Components

One of the primary advantages of the GiroDisc two-piece rotor system is long-term serviceability.

When the cast-iron friction rings reach their service limit, the existing GiroDisc aluminum hats can be retained as long as they remain serviceable.

Simply replace the rotor rings and mounting hardware rather than purchasing another complete set of rotor assemblies.

For GT3 Cup and GT4 Clubsport cars that consume brake rotors regularly during racing and track use, this can significantly reduce long-term brake-system operating costs.

Replacement Hardware Included

GiroDisc supplies these replacement rings as a pair with new replacement hardware.

The only components reused from your existing GiroDisc rotor assemblies are the aluminum center hats.
