Girodisc 325mm Two-Piece Rotor Upgrade for Porsche 981
If you're looking to upgrade your Porsche 981 Boxster or Cayman, let me tell you about the Girodisc system. This isn’t just any rotor swap; it’s a serious upgrade that replaces your factory discs with something that’s built for performance. The Girodisc rotors are slightly larger at 325mm compared to the stock 298mm. What does that mean for you? More braking force and better cooling, which is a game-changer on the track or during spirited drives.
Now, let’s talk materials. The central hat section is crafted from top-notch U.S.-sourced 6061-T6 aircraft aluminum. You know, the kind of stuff that’s lightweight yet incredibly strong. The rotor itself is made from Girodisc's proprietary cast iron, poured right here in the USA and machined in-house. This attention to detail means you're getting a product that not only performs but is built to last.
One of the standout features of these rotors is their 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, whether you’re on a long mountain drive or hitting the track, you can count on consistent performance without the fade.
The floating mount system is where the magic really happens. Using either 8 or 10 high-strength alloy steel drive pins, these are made to Girodisc’s specs and cadmium plated for corrosion resistance. They handle the load during braking while allowing for axial and radial float between the hat and the disc. This means your rotors can self-center between the pads, which is crucial for even wear and performance.
And don’t worry about noise; Girodisc has thought of that too. The pins are mounted with anti-noise spring washers, which allow the rotor to expand with heat but keep things quiet when you’re just cruising around town.
Once you’ve got the Girodisc system installed, replacing the cast iron rotor when it’s worn out is a breeze. It’s sold in pairs, so you can upgrade both the front or rear of your ride, whether it’s a 2013-2016 Boxster or a 2014-2016 Cayman, including the Cayman S.
In short, if you want to enhance your braking performance while keeping it stylish and reliable, the Girodisc 325mm rotor upgrade is a solid choice. Get ready for a noticeable difference on the road!
