Girodisc Rear 380 mm 2-piece Rotor Upgrade

The Girodisc system is a direct replacement for the OE disc on 911 Turbo models with the standard cast iron brake system. No modifications are necessary, allows use of factory unmodified pads unlike most aftermarket solutions for this application. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.

The central hat section of the Girodisc 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 8 or 10 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 grade 12 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.

Fits the following models:
- Turbo or Turbo S models with standard brakes (red calipers) - (991 generation) 2014-2016

Dimensions: 380 x 32 mm. 2-Piece design. Comes with the left and right front rotor. Made by Girodisc. Intended for off road use only. Professional installation required. Racing brake discs need to be regularly inspected by certified mechanics.

Add Girodisc Brake Pads:

GP35 Track Pads
GP35 compound combines the best of both worlds into one all-around race pad. We took some of the longevity of our endurance pads, some of the bite of our sprint pads, and worked to develop a compound that can do it all. As a bonus, it’s easy to bed, which means less time figuring your brakes out, and more time driving on the track.
The GP35 is designed to work with street car ABS as well as motorsport-grade ABS found in factory-built race cars. The torque curve is designed to be smooth and linear, which leads to superior modulation and release under trail braking. These pads work with a wide range of tires, from DOT street tires to R-compounds to full race slicks.
It has become our most popular compound and is the compound we recommend most frequently to track day drivers and shops running cars in professional racing series.
GP10 Street Pads
Designed for performance-minded drivers, our GP10 semi-metallic brake pads strike the perfect balance between daily drivability and occasional track use. Optimized for street conditions, they offer a quiet, lower-dust experience without sacrificing the confident stopping power you need when the pace picks up.
Whether you're navigating traffic or hitting the occasional track day, these pads deliver a responsive pedal feel, excellent heat resistance, and consistent braking performance. Built for longevity and reliability, they’re the ideal upgrade for enthusiasts who want everyday comfort with the capability to push harder when it counts.
For drivers planning extensive track sessions or more aggressive track driving, we recommend considering our dedicated race pads, engineered to handle the extreme heat and demands of frequent high-performance track use.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
Warranty claims must be processed in person at an authorized Porsche Service Center
Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual.

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
A completed warranty certificate
Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.
