The Girodisc system is a direct replacement iron rotor for the OEM PCCB disc, no modifications are necessary. The disc will bolt directly to the car and work with OEM calipers and pads perfectly.
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. 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 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 12 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 center between the pads.
Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
The Girodisc system is a direct replacement for the OE disc however you must use the same pad shape that is used on the 991 GT3 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. If we manufactured a rotor with the same annulus as the OEM PCCB rotors they would be unnecessarily heavy.

DEVELOPMENT: SOUL sought out to maximize performance and boost response while minding clearance on daily driven cars. The optimized 3 into 1 merge collector design improves response over the poor factory design, while the runners ultimately increase exhaust velocity into the collector and turbo. Looking into the factory headers you will notice a support in the middle runner which is detrimental to a smooth flow path out of that exhaust port – all in all the design is very basic with lots of room for improvement. The factory turbo inlet measures around 1.54” ID and we sized our header outlet to 1.63” for a smooth flow path into the turbo. The internal volume of the header combined with the resulting design improvements pairs well with the efficiency map of the turbo giving you noticeably quicker boost response and more power throughout the RPM range. Pushing the gas pedal down commands faster feedback from the car and each gear has more usable power before a downshift.
The factory header utilizes a double wall design while our design is single wall yielding in a more pleasing, sharper edge to the exhaust and increased turbo sound. Exhaust volume and tone quality are delightfully increased without yielding drone or undesirable qualities. Expect more burbles and sharper pops between shifts and on deceleration.
POWER: Below are the real, unedited, straight from the Mustang dyno results as conducted by Apex Autoworks with before and after runs on a Base model Carrera already equipped with SOUL Sport Catalytic Converters and SOUL Performance Exhaust with COBB Accessport Stage 2 Map. This dyno chart is made of the average performing charts of 3 before and 6 after runs. Max power gains of 12 whp and 20 ft-lbs come in quickly and hold until redline for a noticeable increase in driving performance. A custom Pro Tune would further take advantage of the increased flow and unlock greater gains.
CONSTRUCTION: Each set is assembled in house in the USA out of laser cut flanges and mandrel bent, thick wall .065″” T304L stainless steel. Back purged TIG welding (with ARCAL™ Prime argon gas) ensures proper weld penetration and longevity. We fabricate these headers using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.
BOLT ON AND GO: Every component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition. New high grade hardware and OEM Porsche gaskets are included for installation.
