Girodisc A1-168 Girodisc 2pc Front Brake Rotors (Gallardo Super Trofeo) $1,850.00

These Girodisc rotors are a direct replacement for the OE rotors on the Super Trofeo with the addition of the provided caliper spacers. At 380mm diameter, these Girodisc rotors are slightly larger than the 365mm OEM rotors. The Girodisc front rotors are 24.5 lbs vs. 27.0 lbs for the stock units. By upgrading your brakes with lightweight, high performance replacements as opposed to a big brake kit, your factory brake bias and ABS effecitveness are not compromised. The reduction in rotational and unsprung weight allows for quicker acceleration, better brake feel, and more precise suspension response. The central hat section of the Girodisc rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The disc is made from Girodisc'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 forcing cool air through the disc. The disc and hat have a floating mount system, which utilizes 12 high-strength alloy steel drive pins, manufactured in the US by Girodisc and cadmium plated for long-lasting corrosion resistance. These pins take the loads from braking while maintaining the axial and radial float between the hat and disc. They are secured by class 12.9 cap screws and hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs on the disc side, allowing the iron disc to expand as it heats up while eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the brake pads. Once the Girodisc system is in place, you simply replace the cast iron discs when needed. This reduces cost over time by allowing you to re-use the aluminum central hats. Sold/priced per pair
