Girodisc A2-266 Girodisc 2pc REAR Brake Rotors GT4 ClubSport $2,482.00
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 Competition Motorsport RF1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum.  The disc is manufactured from cast iron which is constructed in the USA and is 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 eight to ten high strength alloy steel drive pins manufactured by Girodisc in the USA to our 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 rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

Girodisc A2-272 Girodisc 2pc Rear Brake Rotors for Porsche (oem steel) $2,482.00
Girodisc A2-272 Two-Piece Floating Rear Brake Rotors Fits The Following Cars (oem steel Rotors): Porsche 992 GT3, Rear Porsche 992 GT3RS, Rear Porsche 718 Cayman GT4RS, Rear The Girodisc system is a direct replacement for the OEM rear cast iron rotors on the Porsche 992 GT3 & GT3RS and the 718 GT4RS. No modifications are necessary, allowing use of unmodified factory pad shapes unlike most aftermarket solutions for these Porsches. The Girodisc rotors will bolt directly to your car and work with perfectly with the excellent OEM Brembo calipers. By upgrading your brakes with lightweight, high performance replacements (as opposed to a big brake kit), both the factory brake bias and ABS actuation dialed-in by Porsche engineers are preserved. Girodisc two-piece floating rotors are lighter than the OEM Porsche rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response. When used with Pagid or PFC performance brake pads and CMS RF-1 brake fluid (available from Competition Motorsport), 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.
