A1-272 Girodisc 2pc Front Brake Rotors for Porsche 992 GT3 (OEM Steel) These Rotors Fit The Following Cars (w/ OEM Steel Rotors) Porsche 992 GT3, Front Porsche 992 GT3RS, Front The Girodisc system is a direct replacement for the OEM disc on the 992 Porsche GT3 and GT3RS with OEM iron rotors. No modifications are necessary, allowing use of unmodified factory pad shapes (unlike most racing rotors for this Porsche). The Girodisc rotors will bolt directly to your car and work perfectly with the excellent OEM Brembo calipers. By upgrading your brakes with lightweight, high performance replacements -- as opposed to a big brake kit -- the brake bias and ABS actuation dialed-in by Porsche engineers are preserved. When used with Pagid or PFC performance brake pads and CMS RF-1 brake fluid (available from ), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of each Girodisc 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 class 12.9 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. Features: • Built for racing reliability and consistent performance • Compatible with demanding track environments • Designed for perfect fit and easy installation FAQs: Is this part track-proven? Yes, it has been tested extensively under racing conditions. Does it require professional installation? While not required, professional installation is recommended for best performance. Will this fit my vehicle? Please refer to the fitment guide or contact us to confirm compatibility. Can I return this if it doesn’t fit? Yes, as long as it’s unused and in original packaging.

Race Technologies Racing Brake Pads RT RE10 COMPOUND1 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, Race Technologies RE10 offers consistent performance in the most demanding environments. Typical applications include professional endurance racing, club racing, and HPDE on high braking demand platforms. RACING PAD NOTES: Running a "racing use only" pad on the street could produce excessive noise and dust. Rotor wear could be accelerated if driven at consistently 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 tested on a brake dynamometer over repeated brake applications to test the materials in a controlled environment. Real-world wear rates and temperatures will be influenced by car setup, grip levels, track layout and other variables. Note 1: "RE" denotes a "racing use only" pad compound.
