A1-276 Girodisc 2pc Front Brake Rotors for Porsche 992 GT3/GT3RS (OEM PCCB) FITMENT: Porsche GT3 (992) w/ factory PCCB Porsche GT3RS (992) w/ factory PCCB This 410mm Girodisc conversion system is a direct front rotor replacement for the Porsche 992 GT3 and GT3RS originally equipped with PCCB brakes. These two-piece floating iron rotors with aluminum hats will bolt directly to your Porsche and work flawlessly with the OEM front calipers. You must use must use the pad shape used on the 992 GT3/GT3RS with iron rotors. The annulus (pad swept height) of these rotors is smaller than the PCCBs to keep rotor weight low and allow far better pad selection. By upgrading your brakes with lightweight, high-performance Girodisc rotors, especially when paired with Girodisc A2-154 rear rotors, your Porsche's factory brake bias and ABS efficiency are maintained. The low rotational mass and unsprung weight of Girodisc rotors allows for quick acceleration and fast transient suspension response. Most racers replace the factory PCCBs with Girodisc rotors to avoid the inevitable damage to fragile carbon-ceramic discs when swapping wheels at the track. We suggest using these rotors with these Pagid 4924 or PFC brake pad profiles normally used in the Porsche 991 GT3 without PCCB. When combined with RF1 Racing brake fluid or the New HALO P1 High Performance Brake Fluid, you'll have an extremely reliable and durable solution to cracked or broken carbon-ceramic rotors at a fraction of the cost of factory PCCBs. The central hat section of the 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 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. 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.

A1-291 Girodisc 2pc Front Brake Rotors for Porsche Cayman GT4RS (OEM Steel) Give your Porsche 718 Cayman GT4RS a serious braking upgrade with the Girodisc A1-291 front rotors. These 2-piece rotors are a direct-fit replacement for the OEM iron rotors and are designed to deliver better heat resistance, reduced unsprung weight, and consistent performance lap after lap. FITMENT: Porsche Cayman GT4RS (OEM steel rotors), Front Unlike many aftermarket track rotors, the A1-291 Girodisc rotors are designed to work with the unmodified factory pad shapes and factory Brembo calipers. No adapters, spacers, or changes are required—just bolt them on and go. The 2-piece construction features lightweight aluminum hats and high-carbon cast iron rings. This design reduces rotational mass and allows the rotor to expand freely under high heat, improving braking response and reducing the risk of cracking under intense use. These rotors are street-quiet and track-tough, making them ideal for high-performance drivers who want both daily usability and track capability. When the rings wear out, just replace them (D1-291) and reuse the hats to save money over time. Sold and priced per pair. Girodisc A1-291 Rotor Features: Direct-fit upgrade for Porsche GT4RS OEM iron rotors Compatible with OEM Brembo calipers and pad shapes 2-piece design reduces weight and improves thermal stability Lightweight 6061-T6 aluminum hats with black anodized finish Replaceable iron rotor rings (D1-291) reduce long-term cost Made in the USA using domestic materials Girodisc A1-291 Rotor FAQs: Do I need to change pads or calipers? No, these rotors are designed to work perfectly with your factory calipers and pad shape. Are these rotors good for track use? Absolutely. They offer superior heat dissipation and reduced weight, making them ideal for repeated high-speed stops. Can I drive with these on the street? Yes, these rotors are engineered to be quiet and smooth enough for daily driving while still delivering track-ready performance. When should I replace the rings? Replace them when they reach minimum thickness or show signs of cracking. The aluminum hats are reusable with new rings (D1-291). If you’re serious about driving your GT4RS the way Porsche intended, the Girodisc A1-291 rotor upgrade delivers the stopping power and thermal control to match.

A2-119 Girodisc 2pc Rear Brake Rotors Fits Lamborghini Aventador The GiroDisc system is a direct replacement for the OEM brake disc.  The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly.  By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.  The Giro Disc rotors are lighter than OEM pieces.  The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and RF-1 brake fluid (also available from Discovery Parts), 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 8-10 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 grade12 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 2-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.
