Girodisc A1-122 Girodisc 2pc Front Brake Rotors (350mm) $1,300.00
PORSCHE 991.2 CARRERA S/4S/GTS WITH OEM STEEL ROTORS The Girodisc system is a direct replacement for the OE disc with the use of the provided caliper spacers. Girodisc rotors are slightly larger than the OEM rotor at 350mm versus 340mm, providing greater braking force and cooling capacity. The Girodisc front rotors are approx 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 our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc's own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc. The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking while maintaining the axial and radial float between the hat and disc. The pins are secured by Class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads. Once the Girodisc system is in place, simply replace the cast iron rotor rings when needed. Sold/priced in pairs.

PORSCHE 991 GT3, GT3RS, AND GT2RS (2014 +) WITH PCCB BRAKES This 410mm Girodisc conversion system is a direct FRONT rotor replacement for the Porsche 991 and 991.2 GT3, GT3RS, AND GT2RS originally equipped with PCCB brakes. These two-piece floating rotors will bolt directly to the car and work with OEM calipers perfectly. You must use must use the pad shape used on the 991 GT3 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 (paired with Girodisc A2-154 rear rotors), your factory brake bias and ABS efficiency are maintained. The low rotational and unsprung weight allows for quicker acceleration and transient suspension response. Most racers replace the factory PCCBs with steel two-piece rotors to avoid the inevitable damage to the fragile carbon ceramic discs when swapping wheels at the track! It is suggested that these rotors are to be used with the Pagid 4924 or PFC brake pad profiles normally used in non-PCCB applications.  When combined with the CMS RF1 Racing brake fluid or the New HALO P1 High Performance Brake Fluid, you will have an amazing, durable solution to cracked or broken carbon-ceramic rotors at a fraction of the cost of the factory PCCBs. The hat of each rotor is machined from 6061-T6 aircraft aluminum. The disc is manufactured from cast iron using the same specs and materials as professional racing organizations. The curved-vane design acts as a centrifugal pump to force cool air through the disc.   The disc and hat mount together using a floating mount system with high-strength alloy steel drive pins and Grade 12 cap screws. The drive pins transfer braking load while maintaining axial and radial float between the disc and hat to accomodate heat expansion. Hardened washers and anti-noise springs eliminate the rattle and noise sometimes associated with floating rotors. The two-piece Girodisc design allows for disc-only replacement (using Girodisc D1-154); the aluminum hats are re-usable. Sold/priced per pair
