We provide instructions and a video on how to do this. Other than that the discs will bolt directly to the car and work with the Brembo \"18Z\" calipers perfectly. The Girodisc front rotors weigh 19.5lbs a piece, which are lighter than the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eInstall your OEM Brembo 18Z Calipers with ease utilizing \u003ca href=\"https:\/\/www.9tperformance.com\/products\/copy-of-girodisc-18z-front-lightweight-rotors-audi-brembo-18z-6-pot-caliper-conversion\"\u003eGiroDisc 18Z Front Hardware Installation Kit\u003c\/a\u003e. \u003cbr\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe 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.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe 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 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.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eOnce the Girodisc system is in place, simply replace the cast iron rotor when needed with \u003ca href=\"https:\/\/www.9tperformance.com\/products\/girodisc-18z-front-lightweight-replacement-rotor-rings-audi-brembo-18z-6-pot-caliper-conversion\"\u003eGiroDisc Front Lightweight Replacement Rotor Rings\u003c\/a\u003e.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eSold\/priced in pairs.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e***Please Note - These rotors only fit the B5\/B6\/B7 A4\/S4, C5 A6, and C5 Allroads.
