This system is a direct replacement for the OE discs, with the addition of the included caliper spacers and bolts. Rotor diameter increases to 350 mm from the factory 330 mm, delivering improved braking torque and greater thermal capacity for consistent performance. A1-153 Vehicle fitment • Porsche 911 Carrera (non-Turbo) with standard 330 mm front brakes (front axle).• Porsche 981 / 718 Cayman & Boxster with standard 330 mm front brakes (front axle).• Supplied spacers and bolts adapt OEM calipers to the larger 350 mm Girodisc rotors. Note: Always verify wheel and caliper clearance when upsizing to 350 mm rotors. Lightweight, high-performance rotor engineering The rotor hats are precision-machined from U.S.-sourced 6061-T6 aircraft-spec aluminum. The iron rotor rings are cast in the USA using Girodisc’s proprietary high-carbon iron alloy, then machined in-house for exacting tolerances. A curved vane design actively pumps cooling air through the disc under braking, improving fade resistance during demanding use.

A1-154 Girodisc Two-Piece 410mm Front Brake Rotors FITMENT: Porsche GT3 (991) w/ factory PCCB Porsche GT3RS (991) w/ factory PCCB Porsche GT2RS (991) w/ factory PCCB Porsche GT4RS (718) w/ factory PCCB This 410mm Girodisc conversion system is a direct front rotor replacement for the Porsche 991.1 or 991.2 GT3, GT3RS, GT2RS, and GT4RS 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 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 Competition Motorsport 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.

A1-156 Girodisc Two-Piece 410mm Front Brake Rotors   This Girodisc system is a 410mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for your car's OEM PCCB brakes1. The Girodisc A1-156 will bolt directly to your Porsche and work perfectly with your OEM calipers. There are two main reasons for replacing your PCCB: first, Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the machined cast iron rotor rings are far more durable than the fragile PCCB rotors. This is critical when you're swapping wheels on-and-off the car for track days or racing. It's so easy to nick a carbon rotor and take a chunk out of it, rendering it useless. Pair these Girodisc rotors with Girodisc A2-156 rear rotors to maintain your factory brake bias and ABS efficiency. When used with Pagid or PFC performance brake pads, and CMS RF1 brake fluid, you have an excellent solution to easily cracked carbon-ceramic rotors. The central hat section of the Girodisc is made from 6061-T6 aircraft specification aluminum.

Sold/priced per pair. 1 Note: you must use the same pad shape as that used on the Porsche 991/992 GT3/Turbo with factory iron rotors. The annulus (pad swept height) of these pads is smaller than that of the large PCCB pads.

Sold/priced per pair. 1 Note: These Girodisc rotors have a different annulus (pad swept area) than the OEM CCM rotors, to maintain their light weight. A brake pad with an annulus of 66mm or less must be used with these Girodisc rotors. The necessary pad shape is very common, found on the Nissan GT-R, Cadillac CTS-V, and most AMG Mercedes equipped with six-piston calipers. If there's a specific pad and/or compound you're after please, contact us at (844) 438-7244 and we'll get you what you need!
