PFC 08 COMPOUND
One of PFC's most popular compounds which came to fame in Endurance Sports Car and GT racing due to its performance in applications where smooth initial bite is a must. PFC 08 has a slight friction rise with temperature, excellent release and modulation characteristics.
Despite its considerable performance, PFC 08 has the lowest wear rate of all PFC compounds and can easily match the wear characteristics of competitors' materials but with much higher bite and more consistent performance across a broad temperature range.

FITS: PORSCHE 911 C2/C4 (1999-2008)
Discovery Parts is an Authorized dealer for GiroDisc products and we are one of the largest stocking dealers in the country. We ship most products same or next business day to ensure we meet your delivery deadline.
The GiroDisc system is an upgrade to a 325mm 2-piece steel rotor and aluminum hat combination and 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 Discovery Parts RF-1 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 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.

from $1,700.00
FITS PORSCHE 911 GT3& GT3RS / GT2RS (2014+) REAR WITH STEEL BRAKES
The Girodisc system is a direct replacement for the OE disc on the 991 GT3, GT3RS, and GT2RS with OEM iron rotors. No modifications are necessary, allows use of factory unmodified pads unlike most aftermarket solutions for this application. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.
The central hat section of the Girodisc rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from their 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 12 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 actions 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 when needed.
When used with Pagid or PFC racing brake pads and hi-temp RF1 racing brake fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.
If your car came with OEM center lock wheels please select the center lock drive pin option.

$1,900.00
FITS PORSCHE 991 GT3, GT3RS, GT2RS (2014+) WITH PCCB BRAKES
This 390mm Girodisc conversion system is a rear rotor direct replacement for the Porsche 991 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.
By upgrading your brakes with these lightweight, high-performance Girodisc rotors (paired with the A1-154 front 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!
When used with Pagid or PFC performance brake pads and Discovery Parts RF1 Racing brake fluid, you have an amazing, durable solution to cracked or broken carbon-ceramic rotors at a fraction of the cost of replacing the factory PCCB units.

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.
