A1-019 Girodisc 2pc Front Brake Rotors (350mm)
Girodisc A1-019 Girodisc 2pc Front Brake Rotors (350mm) $1,350.00
A1-019 Girodisc 2pc Front Brake Rotors (350mm) FITMENT: Direct replacement for Porsche 997.1 and 996 GT2/GT3 factory iron front rotors is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline. This Girodisc system upgrades your Porsche's OEM brakes to a two-piece steel disc and aluminum hat. This two-piece "floating rotor" design will bolt directly to your GT2 or GT3 front and work flawlessly with the OEM calipers. Upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Each rotor is 5.6 pounds lighter than an OEM rotor, reducing rotational and unsprung mass giving you stronger braking and faster suspension response. Combined with Pagid or PFC performance brake pads and RF-1 brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving. The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc. The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors. This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs. Sold/priced per pair.

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.

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.

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 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, 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.
