Girodisc Front Slotted 2pc Rotor Set for EVO X
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 19.4lbs 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 our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our 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 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. 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 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.

Customer Reviews
Really well made, performs amazingly, and they look awesome.
These front rotors come with the updated 6061-T6 central hats, coated in black (instead of blue). The floating cast iron discs are mounted with anti-noise washers, which have pleasantly surprised me by being as quiet as non-floating, solid rotors. Also, the weight savings made the car feel noticeably lighter-footed. Overall, these Girodisc front rotors are arguably the best choice for our Evo X.
Key points from the in-box installation instructions:
[1] Do NOT tighten or loosen the fasteners on the rotor.
[2] Ensure the bolts and lines are properly tightened and connected.
[3] Ensure the brake pad with the "squeal tab" is on the inboard side.
[4] The rotors are directional. Looking at the upper half, the surface slots must lean towards the front (so the hidden vanes lean towards the back) of the car.
This brake rotors work great for daily driving . This product came fast thanks to MAPerformance , they were easy to install love this product
These things are great, they look great, the feel great! The Evo X is a heavy car, reducing unsprung weight makes a HUGE difference and managing brake temps is crucial on the track. These have held up very well after years of street driving and track use.
Great discs, they save considerable weight and increase breaking power. They also look beautiful.
