    Girodisc Front Slotted 2pc Rotor Set for EVO X - Modern Automotive Performance

    The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Girodisc front rotors are approx 17.4lbs vs. 23.5lbs for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.

    The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron to the same specification and material as used by professional racing organizations. It is 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 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. 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 rotor when needed.

    When used with performance pads and hi-temp fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.

    Whole car improvement.

    Super light weight compared to the stockers. I noticed a change in suspension response, steering response, braking and acceleration. They are expensive, but I honestly think they are the best "bolt-on" I've installed so far, mainly because the rotors improve so many aspects of the car. Get them!

    Bad to the Bone...

    These rotors are like works of art, they look so good that I really don't want to put them on the car. I'm just kidding of course, but they are amazing and the quality is "First Class" all the way. I highly recommend these to every Evo owner.

    I can stop again!

    Love the new setup! Light weight and love the stopping power these throw down! Great customer service and fast shipping!


    These rotors are awsome, there light weight and work extremely well with st43's

    These things are awesome

    These things are crazy light & great quality. I almost didn't want to put them on my car. I would definitely suggest them.
