Discontinued New old stock rotor. These have the straight grooves as images show, not the new curved grooves. Final Sale, no returns or exchanges.
This Girodisc system is a direct replacement for OEM Porsche steel (cast iron) rotors1 with the use of the provided caliper spacers. The Girodisc rotors are slightly larger than the stock Porsche rotors at 350mm vs. 340mm, providing greater braking force and cooling capacity. The Girodisc front rotors are approximately 21.0 lbs. vs. 24.4 lbs. for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.
The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.
The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by Grade-12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.
The two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.
Sold/priced per pair.
1 Note: this Girodisc kit does not fit Porsche models with factory PCCB brakes.

Ferodo Compound DS3.12
The DS3.12 is the latest evolution in Ferodo's incredible DS line. Sports cars today have more of everything: more horsepower, more sophisticated aero, higher curb weights, and stickier tires. These attributes place serious demands on a vehicle's brake system. The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly handle those demands.
Ferodo Compound DS1.11
The DS1.11 has a lower mu than the DS3.12 at all temperatures and can be characterized as a moderate mu pad vs. other endurance racing compounds. They require more pedal force than the DS3.12, and they have a slightly declining torque curve as temperatures rise. As they get hotter and you dive deeper into a turn, you may feel like you need to push a little harder on the brake pedal to elicit the same response (which is a feel many drivers actually prefer). Some drivers feel that the DS1.11 is more controllable on street tires than DS3.12 since ABS cannot be activated as easily. It will last a fairly long time vs. many other pad compounds on the market but does not last quite as long as the DS3.12. They are very gentle on discs at track temperatures when a proper pad transfer layer is maintained. The DS1.11 also has an outstanding max temp and fade resistance, just not quite as high as 3.12. We're not aware of anyone who has faded them, and most people differentiate between the DS1.11 and DS3.12 based on feel.
Ferodo Compound DS2500
Although we always recommend using a dedicated race pad for the track, the DS2500 is one of the best hybrid street/track pads on the market. It features the moderately high bite and solid fade resistance of a track pad, with the relatively low dust and noise levels of a street pad. When used as a street pad, it can produce some squeal on certain vehicle platforms. If you drive aggressively on the street, do some canyon runs, autocross, and maybe some light track duty on street tires, the DS2500 is tough to beat.
Ferodo 11 FCP4955 Comparison Chart
Out of all the pad compounds we've ever tested, from all manufacturers, the Ferodo DS3.12 shows the flattest torque curve across the broadest temperature range. That means on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same, providing tremendous consistency and repeatability. The DS3.12 has a higher mu (µ) than Ferodo's other compounds, so not as much pedal pressure is required to initiate the desired response. It is also un-fadable, showing no drop in performance at any temperature your brakes will ever see.
Ferodo 11 FCP4955 Coefficient of Friction (Mu) Comparison Chart
In dyno testing, the Ferodo DS3.12 has shown superior wear rates to the other Ferodo compounds, while remaining kind to brake rotors. We believe the Ferodo DS3.12 will become the gold standard by which other race compounds will be judged.

Girodisc GP-Series Brake Pad Overview
The Girodisc GP-Series brake pads in the 1741 shape deliver high-performance braking for Porsche 991, 992, and 718 GT4 applications. Engineered for consistent torque, stable friction, and excellent pedal feel, these pads are available in three compound options to match your driving style—from daily street use to full-time track duty. All three compounds fit the same front calipers and rotor setup, making it easy to select the level of performance you need.
GP10 Street Compound
Designed for spirited daily driving, the GP10 compound offers fast cold bite, low noise, and low dust while maintaining stable performance during aggressive street use.
GiroDisc GP30 - Endurance Race Compound
Built for long stints, the GP30 delivers consistent friction over extended sessions with reduced wear and excellent rotor friendliness—ideal for endurance racing or heavy track use.
GiroDisc GP35 - Race Pad for All Occasions
Our 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.
Note: this compound is only compatible with iron rotors.
Girodisc GP-Series Pad FAQs
Which compound is best for everyday street driving? GP10 is the recommended choice for daily use thanks to low dust, quiet operation, and reliable cold bite.
Are the GP30 or GP35 compounds okay to use on the street? They can be used, but both are optimized for track temperatures and may produce more noise and dust when cold.
Do these pads fit the factory Porsche iron rotors? Yes, all GP-Series 1741 pads are fully compatible with OEM iron rotors as well as Girodisc two-piece steel rotors.
Do these pads require a bedding procedure? Yes, proper bedding is necessary to establish an even transfer layer and achieve maximum performance.

Ferodo Compound DS3.12
The DS3.12 is the latest evolution in Ferodo's incredible DS line. Sports cars today have more of everything: more horsepower, more sophisticated aero, higher curb weights, and stickier tires. These attributes place serious demands on a vehicle's brake system. The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly handle those demands.
Ferodo Compound DS1.11
The DS1.11 has a lower mu than the DS3.12 at all temperatures and can be characterized as a moderate mu pad vs. other endurance racing compounds. They require more pedal force than the DS3.12, and they have a slightly declining torque curve as temperatures rise. As they get hotter and you dive deeper into a turn, you may feel like you need to push a little harder on the brake pedal to elicit the same response (which is a feel many drivers actually prefer). Some drivers feel that the DS1.11 is more controllable on street tires than DS3.12 since ABS cannot be activated as easily. It will last a fairly long time vs. many other pad compounds on the market but does not last quite as long as the DS3.12. They are very gentle on discs at track temperatures when a proper pad transfer layer is maintained. The DS1.11 also has an outstanding max temp and fade resistance, just not quite as high as 3.12. We're not aware of anyone who has faded them, and most people differentiate between the DS1.11 and DS3.12 based on feel.
Ferodo Compound DS2500
Although we always recommend using a dedicated race pad for the track, the DS2500 is one of the best hybrid street/track pads on the market. It features the moderately high bite and solid fade resistance of a track pad, with the relatively low dust and noise levels of a street pad. When used as a street pad, it can produce some squeal on certain vehicle platforms. If you drive aggressively on the street, do some canyon runs, autocross, and maybe some light track duty on street tires, the DS2500 is tough to beat.
Ferodo 11 FCP4713 Comparison Chart
Out of all the pad compounds we've ever tested, from all manufacturers, the Ferodo DS3.12 shows the flattest torque curve across the broadest temperature range. That means on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same, providing tremendous consistency and repeatability. The DS3.12 has a higher mu (µ) than Ferodo's other compounds, so not as much pedal pressure is required to initiate the desired response. It is also un-fadable, showing no drop in performance at any temperature your brakes will ever see.
Ferodo 11 FCP4713 Coefficient of Friction (Mu) Comparison Chart
In dyno testing, the Ferodo DS3.12 has shown superior wear rates to the other Ferodo compounds, while remaining kind to brake rotors. We believe the Ferodo DS3.12 will become the gold standard by which other race compounds will be judged.

RE10 COMPOUND
Race Technologies RE10 is the ultimate endurance race compound, offering a balance of excellent stopping power, low thermal conductivity, and extremely low pad and rotor wear. Utilizing the latest friction material technology, RE10 offers consistent performance under the most demanding of environments.
Typical Applications: Professional Endurance Racing, Club Racing, and HPDE on high demand brake platforms.
TS20 COMPOUND
The Race Technologies TS20 is the ideal dual purpose compound for street and light track use. The TS20 combines an aggressive initial bite, good heat resistance all while keeping dust and noise to a minimum.
Note: RE10 is a "racing use only" pad.
Running a "racing use only" pad on the street could produce excessive noise and dust.Disc wear could be accelerated if driven at cold temperatures or used in the incorrect temperature range.
Racing pads are designed to work in specific temperature ranges, so it's important to choose the right compound for the environment the vehicle will be used in.
Pad compounds are run on a brake dynamometer over multiple brake applications ("stops") to test the materials in a controlled environment and obtain accurate data. Wear rates and operating temperatures can be influenced by car set-up, grip levels, track layout, and other variables.
