If you’re looking to upgrade your Porsche’s braking system without diving into a full big brake kit, the Girodisc rotors are a solid choice. These are direct replacements for your factory discs—no need for any modifications, just bolt them right on and you’re good to go. They fit perfectly with your OE calipers, so you won’t have to worry about messing with your car's braking balance or ABS performance.
One of the standout features of the Girodisc system is the central hat section, crafted from top-notch U.S. sourced 6061-T6 aircraft aluminum. It’s not just lightweight; it’s durable and built to last. The rotors themselves are made from Girodisc’s proprietary cast iron, which is poured and machined right here in the USA. This isn’t some off-the-shelf stuff; it’s designed with performance in mind, and you can feel that difference when you hit the brakes.
The rotor design is pretty clever, too. With a curved vane setup, it acts like a centrifugal pump, pushing cooling air through the disc to keep things from overheating during spirited drives. That’s a game-changer if you’re pushing your Porsche to its limits.
Now, let’s talk about the mounting system. The rotors and hats use a floating mount design that’s secured with 8 or 10 high-strength alloy steel drive pins. These are made in the USA to Girodisc’s own specs and are cadmium plated for corrosion resistance. This setup not only handles the load during braking but also allows for axial and radial float, which is crucial for performance. You won’t have to deal with annoying rattles either, thanks to the anti-noise spring washers that keep everything quiet when the rotors are cold.
When it’s time for a rotor replacement, it’s a breeze—just swap out the cast iron rotor, and you’re back in action. The Girodisc system is priced per pair, so you can upgrade both sides of your ride.
These rotors are a perfect fit for:
Whether you’re hitting the track or just enjoying a spirited drive on your favorite backroad, the Girodisc rotors will give you the confidence and performance you’re looking for. They’re built for enthusiasts, by enthusiasts.
