GiroDisc Porsche 997 Carrera PCCB-to-Iron Front Brake Conversion – Slotted Rotors

Description

GiroDisc Porsche 997 Carrera PCCB-to-Iron Front Brake Conversion

Replace the factory Porsche Ceramic Composite Brake (PCCB) front rotors on compatible Porsche 997 Carrera models with GiroDisc’s two-piece floating cast-iron brake rotor system.

The GiroDisc A1-032 provides a serviceable alternative to expensive ceramic brake rotors, making it an attractive option for Porsche owners who regularly participate in track days, driver education events, and other high-performance driving activities.

Designed for the appropriate factory brake configuration, these slotted front rotors use the GT3/Turbo-style brake pad shape.

Convert from PCCB Ceramic to Cast-Iron Rotors

Factory Porsche Ceramic Composite Brakes offer excellent performance, but replacement ceramic rotors can be expensive, particularly on cars subjected to repeated track use.

The GiroDisc A1-032 system replaces the ceramic friction discs with high-performance cast-iron rotors featuring lightweight aluminum center hats.

For track-driven vehicles, this conversion provides several practical advantages:

• Replaceable cast-iron friction rings
• Access to a wider range of compatible iron-rotor brake pad compounds
• Serviceable two-piece rotor construction
• An alternative to replacing costly factory ceramic discs

Important: GT3/Turbo Brake Pad Shape Required

This rotor application requires the correct GT3/Turbo-style brake pad shape.

The brake pad shape and friction material must be appropriate for the GiroDisc iron rotor system.

Do not assume the existing PCCB pads can be reused. Pads designed specifically for ceramic rotors may not be suitable for cast-iron brake discs.

Before ordering, verify the vehicle’s brake calipers and the required pad shape. Demon Speed Motorsports can help identify compatible performance or racing brake pads.

Two-Piece Floating Rotor Construction

Each GiroDisc rotor uses a proprietary cast-iron friction ring mounted to a lightweight aluminum center hat.

The center hats are machined from 6061-T6 aluminum, reducing weight compared with traditional iron-hat rotor construction.

High-strength floating drive hardware allows controlled movement between the friction ring and center hat as the rotor expands under braking temperatures.

This design is particularly beneficial during repeated heavy braking, when temperature changes can be substantial.

Curved-Vane Internal Cooling

GiroDisc’s cast-iron friction rings incorporate curved internal cooling vanes designed to promote airflow through the rotor.

The internal vane geometry helps move cooling air through the disc during rotation, assisting with thermal management during demanding driving conditions.

Slotted Friction Surface

The slotted rotor surface helps refresh the brake pad contact area and clear debris from the pad-to-rotor interface.

The slotted design also avoids the drilled-hole stress concentrations associated with some cross-drilled rotor designs.

Replaceable Friction Rings

Once the GiroDisc system has been installed, the cast-iron friction rings can be replaced independently of the aluminum hats.

Provided the center hats and mounting components remain serviceable, owners can retain the original GiroDisc hats when replacing worn friction rings.

This is a practical benefit for track-driven cars that require regular brake maintenance.

Important Fitment Information

This is a specialized brake rotor application and should not be treated as a universal replacement for every Porsche 997 Carrera.

Confirm that the vehicle has the appropriate PCCB brake configuration and GT3/Turbo-style pad arrangement.

Vehicles equipped with standard steel brakes, modified calipers, or different PCCB systems may require another GiroDisc rotor assembly.

The correct iron-compatible brake pads must be used. Verify front and rear brake system compatibility before performing a complete PCCB conversion.

Contact Demon Speed Motorsports for assistance confirming the correct rotor and pad combination.
