Girodisc Front Replacement Rotor Rings – Porsche 981 / 991 (Steel Brakes)

The Girodisc Front Replacement Rotor Rings & Hardware Kit is designed for Porsche models equipped with Girodisc two-piece front brake systems, allowing you to replace worn friction rings without the need to purchase new aluminium bells.

Manufactured from high-quality cast iron with a curved vane design, these replacement rotors deliver excellent heat management, consistent braking performance and durability under demanding fast road and track use. Designed as a direct replacement for existing Girodisc assemblies, they retain full compatibility with your original bells and mounting points.

This kit includes new bobbins and mounting hardware, ensuring correct float and long-term reliability when replacing worn friction rings. It’s a cost-effective solution for maintaining peak braking performance while reducing long-term running costs.

Once the Girodisc kit is in place, simply replace the disc/rotor when worn (new hardware included on replacement discs/rotors, bells do not need replacing). Sold/priced per pair.
