If you're looking to upgrade your Porsche 991.2's braking performance, the Girodisc system is a solid choice. This isn’t just some generic rotor; it’s a direct replacement for the OEM PCCB disc, and you won’t need to fuss with any modifications. Just bolt it right on, and you’re good to go’your OEM calipers and pads will fit like a glove.

What really sets these rotors apart is their construction. The central hat section is crafted from U.S.-sourced 6061-T6 aircraft-grade aluminum, which not only keeps things lightweight but also adds a touch of durability. The disc itself is made from a proprietary cast iron, poured and machined right here in the USA at Girodisc. You can feel the quality in every turn of the wheel.

One standout feature is the curved vane design. This isn’t just for looks; it’s been developed through racing experience to act like a centrifugal pump, pushing cooling air through the disc. So, whether you're on the track or just cruising, you’ll notice better heat management and performance.

  • The rotor and hat are connected via a floating mount system, held together by 12 high-strength alloy steel drive pins. These aren’t just any pins; they’re made to Girodisc’s own specifications and cadmium plated for long-lasting corrosion resistance.
  • These pins handle the load during braking but still allow for axial and radial float between the hat and disc, which is crucial for performance.
  • Secured by class 12.9 cap screws with hardened washers, you can trust that everything stays tight and secure.
  • To avoid any annoying noise when things are cold, the pins are mounted with anti-noise spring washers. This clever design lets the rotor expand with heat while keeping the rattles at bay.
  • Thanks to this floating setup, the rotor self-centers between the pads, which is a nice touch for consistent braking.
  • And when it’s time for a change, you can easily replace just the cast iron rotor without having to swap out the whole system.
  • Oh, and they come priced in pairs, so you’re all set for both sides.

As for fitment, these rotors are designed specifically for the Porsche 991.2 C2, C4, and Carrera models from 2017 to 2019. If you want to elevate your ride's braking performance without any hassle, the Girodisc floating cast iron rotor conversion is definitely worth considering.
