Brake Upgrades

More and more Porsche owners are contacting us to talk about brake upgrades and replacements. While original Porsche brake components are of a very high quality, there are ways that they can be improved.

Porsche owners wishing to upgrade their braking system are not always hard core track drivers. In fact, the majority of drivers are simply asking for a more responsive brake feel and a brake disc that maintains it’s appearance and doesn’t corrode over time if the car is driven infrequently.

Girodisc Brake Upgrades

The Girodisc system is a direct replacement for the Porsche OE disc with the addition of provided calliper spacers and longer bolts. The rotor is slightly larger than the Porsche OEM rotor providing greater braking force and cooling capacity.

The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminium. The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilises 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 utilises 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our 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 class 12.9 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.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
