Porsche 991.2 Carrera - GiroDisc PCCB to Iron Rotors Conversion
Description
The Girodisc system is a direct replacement for the OE disc however you must use the same pad shape that came with the iron rotors from the factory. The annulus (pad swept height) of these pads is smaller than the large PCCB pads, this is done to keep the rotor weight at a reasonable level and allow far better pad selection.
MATERIALS: The central hat section of the rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminium. The disc is made from their own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc.
The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc. The rotor and hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc.
The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self centre between the pads.
ABOUT GIRODISC
GiroDisc is guided under the direction of company Principal Martin Meade, who spent five years as an Engineer with Porsche Engineering Services, where he played a role in developing current Porsche technology. Martin began his engineering career working in Aerospace, developing tools and components for special projects.
Before working with Porsche, Martin learned a great deal about vehicle design and technologies by working with several vehicle design and development firms. Martin has enlisted help from key sources such as a former Road Testing engineer and Design Engineer for Brembo North America in the High Performance division, Eric Dahl.
With lessons learned at Brembo, and experience in prototype and racing car design, Eric has developed a broad spectrum of engineering capabilities in the world of high performance automobiles, and specifically the technologies for developing braking systems. GiroDisc designs and engineers the replacement discs after documenting and studying the OE brake system and specifically the disc design.
After analysing the data and determining how best to maximize the benefit of the new disc, the design process is carried out using 3D CAD-CAE (Computer aided drafting, Computer aided engineering). Prototypes are constructed and tested with a vehicle. When the GiroDisc team is satisfied that the disc will meet the goals established for the vehicle, only then will it be released for sale.
SLOTTED EDGES
The edges of the slots continuously clean and refresh the pad surface. This will allow the pads to have a maximized friction surface always available. Additionally, they prevent contaminants from collecting between the pad and disc interface. The disc is lightened, decreasing its rotational inertia. Slots prevent the formation of a water film on the disc in wet weather, maintaining the best brake response.
GiroDisc iron rotors are a cost effective premium brake replacement solution to expensive carbon ceramic rotors and make an ideal solution for track day use.
DETAILS:
+ Fits all Porsche 991.2 Carrera vehicles (2017-2019) with PCCB rotors – this is a conversion kit
+ Perfect solution for vehicles seeing track use – saving you from costly OE ceramic replacements
+ 410mm front, 390mm direct replacement 2-piece rotors
+ Improved braking performance through increased cooling efficiency
+ Reduced unsprung weight
+ Premium quality; made in U.S.A.
