Porsche 991 Parts & Accessories

Shop Porsche 991 parts for brake service, a rotor project or specialist engine and axle work. Compare GiroDisc rotors, service rings and caliper-rebuild references with ACL bearings, GSC springs and a DSS axle reference. Choose the exact Carrera, Turbo or GT application before selecting the component.

GiroDisc Rotors, Rings and Caliper Service

The selection separates complete rotors from replacement rings for factory hats and caliper-rebuild kits. Choose the service job first: replacing a complete assembly, renewing a compatible ring or servicing the correct caliper. S/4S/GTS, GT3 and competition references have different coverage and must be matched to the installed brake system.

PCCB-to-Iron Conversion References

Some GiroDisc titles explicitly describe iron-rotor conversions for specified PCCB-equipped applications. Review the exact vehicle, caliper, axle, compatible friction and complete conversion requirements before choosing a package. A conversion reference is a different project from a direct replacement for an existing iron-rotor system.

Engine and Axle Project Components

ACL rod-bearing and GSC spring references identify Turbo engine work, while DSS lists a separate rear-axle application. Match these parts to the actual engine or driveline with the installer or builder. Measured clearances, supporting valvetrain components and exact axle interfaces determine the appropriate selection.

Choose Your Part

• Choose the exact 991 variant and service project.
• Identify the engine and original or converted brake and driveline equipment.
• Compare complete assemblies with rings, rebuild pieces and specialist components.

Frequently Asked Questions

Are GiroDisc rings complete rotors?

No. Ring references require the stated compatible hats and system. Review hardware and exact application.

Does a caliper-rebuild kit fit every 991 caliper?

No. Match the particular caliper and brake-package application.

Is a PCCB-to-iron conversion an ordinary rotor replacement?

No. Review the complete conversion requirements and supported vehicle and brake equipment.

Will Turbo engine-build references cover all Carreras?

Do not assume so. Confirm the exact engine and builder’s component specifications.

How should I choose the DSS axle reference?

Match the exact vehicle, drivetrain, axle position and installation interfaces specified by the manufacturer.
