If you're looking to upgrade your braking game, the Girodisc system is where it's at. This isn’t just another set of rotors; it’s a direct replacement for your OE discs, but with a twist. We throw in some caliper spacers and longer bolts so you can fit those beefy 350mm rotors without breaking a sweat.

Now, let’s talk materials. The central hat section of these rotors is crafted from top-notch U.S.-sourced 6061-T6 aircraft aluminum. Seriously, this stuff is used in aviation for a reason’it's lightweight but tough. The disc itself? That’s our proprietary cast iron, poured right here in the USA and machined from start to finish at Girodisc. You can trust that we know what we’re doing.

One of the standout features is the curved vane design. This isn’t just for looks; it’s engineered to act like a centrifugal pump, pushing cooling air through the disc. So, if you’re hitting the track or just cruising through the canyons, you can count on these rotors to stay cool under pressure.

And let’s not overlook the floating mount system. It’s got 10 high-strength alloy steel drive pins, all made in the USA to our specs and cadmium plated for that extra layer of corrosion resistance. These pins handle the load when you hit the brakes while allowing for axial and radial float between the hat and the disc. No more worrying about wear and tear, right?

To keep things quiet during those chilly mornings, we’ve added anti-noise spring washers on the rotor side. These little guys let the rotor expand with heat but keep the annoying rattle at bay. Plus, this float means the rotor can self-center between the pads, giving you a smoother braking experience.

Once you’ve got the Girodisc system installed, swapping out the cast iron rotor when it’s time for a change is a breeze. It’s sold in pairs, so you’ll be all set for your Porsche 991.1 Carrera S, 4S, or GTS. Just remember, this isn’t a one-size-fits-all; it’s precision-engineered for your ride. Upgrade your brakes and feel the difference!
