A1-239 Girodisc 2pc Front Brake Rotors for Camaro ZL1 (Gen 5) FITMENT: Chevy Camaro ZL1 (Gen 5) 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 two-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake rotors. These two-piece floating rotors will bolt directly to the car and work with your OEM calipers perfectly. By upgrading your brakes with these lightweight, high-performance replacements (as opposed to a big brake kit), your factory brake bias is maintained, along with your ABS efficiency. Girodisc two-piece floating rotors are lighter than OEM brake rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response. When used with Pagid or PFC performance brake pads and CMS RF-1 brake fluid (available from ), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of each 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 class 12.9 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.

A1-276 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.

Girodisc A2-008LW Ultralite Rotors MUCH LIGHTER STANDARD GIRODISC TWO-PIECE OFFERING FOR THE EVO 6/7/8/9, INTENDED FOR OFF ROAD USE ONLY! The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. 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 our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our 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 our 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. Sold/priced per pair

FITS: Ferrari 360 Challenge   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 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 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.
