FITMENT (FRONT): Renault Megane III RS (2017+) Discovery Parts is an authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. We ship Girodisc systems worldwide on the same or next business day to ensure we meet your delivery deadline. This 350mm Girodisc system is a direct replacement for the OE Renault rotors, no modifications are necessary. The rotors will bolt directly to the car and work with OE calipers perfectly (using the supplied billet spacers to accommodate the 10mm larger Girodisc rotors). By upgrading your brakes with lightweight high performance replacements (as opposed to a big brake kit), your factory brake bias is maintained as well as your ABS efficiency. The Girodisc front rotors are approx 22.0 lbs vs. 25.2 lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.The central hat section of our rotor is made from U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from Giorodisc's 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 and cadmium plated for 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 Grade-12 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 discs when needed. Sold/priced per pair.
