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.

A2-266 Girodisc 2pc REAR Brake Rotors GT4 ClubSport This high-performance product is built to meet the demands of competitive racing. Designed for durability, precision, and track-day performance. Engineered for Performance on the Track This Girodisc system is a 380mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for the one-piece OEM GT4 Clubsport steel brakes. The A2-266 will bolt directly to the GT4 ClubSport and work perfectly with your OEM calipers. There are two main reasons for replacing your OEM rotors: first, the Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the slotted Girodisc A2-266 will far outlast the OEM drilled rotors. When subjected to intense heat in a racing or track-day environment, the drilled holes in the OEM rotors originate cracks which can lead to rotor failure. When paired with the Girodisc A1-266 front rotors, your factory brake bias and ABS efficiency are maintained. When used with Pagid or PFC performance brake pads, and RF1 brake fluid (also available from Discovery Parts), you have an amazing solution to overheating, cracking and warping rotors.
