DESCRIPTION
Upgrade the braking performance of your Lamborghini Gallardo Super Trofeo with Girodisc 2-piece Brake Rotors A2-168.
The Girodisc system is a direct replacement for the OE disc. No modifications are necessary—the rotors bolt directly to the car and work with OE calipers. The factory rotors measure 365mm, while these upgraded 380mm discs include the necessary caliper spacers for proper fitment. The Girodisc front rotors weigh approximately 24.5 lbs compared to 27 lbs for the stock units. By upgrading with lightweight, high-performance replacements instead of a big brake kit, you maintain factory brake bias and ABS efficiency. The reduction in rotational and unsprung weight allows for quicker acceleration and sharper suspension response.
The central hat section is made from strictly U.S.-sourced 6061-T6 aircraft specification aluminum. The disc is Girodisc’s proprietary cast iron, poured in the USA and machined entirely in-house. Each rotor features a curved vane design, developed in racing, that acts as a centrifugal pump to force cooling air through the disc.
The rotor and hat are connected with a floating mount system utilizing 12 high-strength alloy steel drive pins, manufactured in the USA to Girodisc specifications and cadmium plated for long-lasting corrosion resistance. These pins handle braking loads while maintaining both axial and radial float between the hat and disc. They are secured with class 12.9 cap screws and hardened washers. To eliminate noise when cold, anti-noise spring washers are installed on the rotor side. These allow thermal expansion while preventing rattle and ensuring the rotor self-centers between the pads.
Once the Girodisc system is in place, simply replace the cast iron rotor when needed.
