No modifications to your car are necessary. The 360mm diameter rotors will bolt directly to your Mercedes AMG and work with the original calipers perfectly.\u003c\/p\u003e\n\u003cp\u003eThe Girodisc front rotors are approximately 23.6 lbs vs. 34.5 lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When upgrading your original brakes with lightweight high performance iron replacements, your factory bias is maintained as well as your ABS efficiency.\u003c\/p\u003e\n\u003cp\u003eThe central hat section of the Girodisc rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is drilled and slotted for incredible cooling, made from Girodisc's proprietary American-made cast iron and machined from start to finish in house at Girodisc. The disc utilizes a curved vane design, developed in racing to act as a centrifugal pump forcing cooling air through the disc.\u003c\/p\u003e\n\u003cp\u003eThe disc and hat are joined by a floating mount system using 12 high-strength alloy steel drive pins manufactured by Girodisc in the USA and cadmium plated for long-lasting corrosion resistance. The drive pins bear the braking load 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, allowing the rotor to grow with heat expansion while eliminating the rattle typically associated with floating rotors. A floating rotor will also self-center between the pads.\u003c\/p\u003e\n\u003cp\u003eOnce your Girodisc system is in place, you can simply replace the cast iron discs as needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eSold\/priced per pair.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"GiroDisc Racing Brakes \u0026 Technologies","offers":[{"title":"Default Title","offer_id":43204460445915,"sku":"A1-022","price":1400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/Girodisc--Brake-Rotors-Dimpled-Slotted-A1-022DS.jpg?v=1759942074"},{"product_id":"a2-022-girodisc-2pc-rear-brake-rotors-2007-2009","title":"A2-022 Girodisc Mercedes 330mm Rear Rotors","description":"\u003ch1\u003eGirodisc Mercedes 330mm Rear Rotors\u003c\/h1\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/9242\/8763\/files\/Girodisc_rear_hero_image.png?v=1760631535\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eGirodisc 330mm rear rotors offer a direct OEM replacement solution engineered for Mercedes performance and reliability.
