SPORTS Brake Disc

Brake Disc / Rotor Slotted 2-pc FRONT




Fits:
Porsche 718 GT4 RS

Brake Disc Type: 2-Piece Slotted

The Girodisc brake rotor is a direct replacement for the OE discs, and provides significant performance benefits. The rotors are compatible with any of the current pads typically used with these cars.

Additional information:

Braking Performance: The rotor is a two-piece design developed in racing to produce a lightweight rotor that can compensate for the different expansion rates between the hat and rotor and eliminate the possibility of rotor warping.

The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, which allows for axial and radial float.

More heat sink without a weight penalty: The Girodisc disc set weights in a little lighter than the OE system but with an important advantage. The rotors have grown in diameter. This means that weight has been transferred from the center hat were it does nothing to the outer diameter where it is actively absorbing and dispersing heat.

High Quality Materials: The Girodisc system uses only the highest quality materials and components. The rotors are high carbon content iron for long wear and stable thermal performance. The top hat section is machined from billet aluminum with an attractive anodized finish. 

This product is a special order item, allow 5 - 7 working days for delivery.

Porsche 992 GT3 excl. PCCB
Porsche 718 GT4 RS

Kit Contains:
Brake Disc complete with centre bell.

Brake Disc Type: 2-Piece Slotted

The Girodisc system is a direct replacement for the OE disc on the 992 GT3 with OEM iron rotors. No modifications are necessary, and it allows the use of unmodified factory pads. The disc will bolt directly to the car and work with factory calipers.

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 12 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.

This product is a special order item, allow 5 - 7 working days for delivery.
