Current news

(Ermelo, The Netherlands – January, 2017) –Advanced Performance Parts, the supplier for high performance and racing brake systems from the brands StopTechCentric, GiroDisc and many more is now also offering GiroDisc’s new Honda Civic Type-R Turbo (FK2) 2-piece rotor upgrade.

 

About GiroDisc 2-Piece Rotor upgrades:
The primary purpose of the GiroDisc system is to reduce unsprung and overall vehicle weight. The secondary purpose is to increase the ventilation and cooling capacity of the brake disc while retaining its original dimensions. This is accomplished by using two-piece disc construction. 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 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. The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring clips 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.

These specific 2-piece rotors give superior braking performance for everyday “Street” styled driving and are ideal for track days giving users that extra braking performance needed to win from the competition.

 

 

What is required to install the GiroDisc system?
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 Brembo calipers perfectly. Once the GiroDisc system is in place, simply replace the cast iron rotor when needed.


How does reducing weight of the braking system benefit the vehicle?
The GiroDisc will generally weigh between 4 – 8 lbs. less than the OE disc it will replace. This is due to the heavy cast iron hat section being replaced with lightweight, high strength aluminum. The mass of any vehicle requires energy to accelerate or decelerate. Reducing the vehicle mass improves acceleration, and requires less energy to be dissipated during deceleration. Rotating mass requires additional energy in order to increase or decrease its speed of rotation. Decreasing the mass of the disc has a great benefit due to reduction in rotational inertia. This will allow more of the braking force to be available to decelerate the vehicle, not the disc.

Additionally, the mass of the brake system is also unsprung mass. Reducing the unsprung mass has the additional benefit of improved suspension performance, resulting in enhanced ride and handling. Rotating masses require additional energy to vary the plane on which they turn. The lighter the disc, the quicker the response of the vehicle steering due to the reduction in gyroscopic effect/rotational inertia of the disc. As an example, compare the weight of the Ferrari 360 OE disc at 18.2 lbs., and the GiroDisc at 14 lbs. The GiroDisc is 4.2 lbs. lighter per disc. Replacing all four discs will save 16.8 lbs. of rotating, unsprung mass.


Ok great, but what type of pads should I use combined with these rotors?
Choosing the correct brake pad starts with an honest assessment of the driver’s typical driving style and conditions. For example, if the vehicle is driven 80 percent in highway commuting conditions, 20 percent on canyon roads, and zero percent on the track, then a StopTech Street Performance brake pad will likely offer the best combination of stopping performance, low dust and low noise.

If the vehicle is frequently used for track days but also as a daily driver, it might be better served by the StopTech Sport Pad – provided that an even transfer layer of pad material on the rotor is maintained by periodically re-bedding in the pads.

These specific 2-piece rotors are not only an upgrade from a 1-piece design to a 2-piece design, they are also larger than the OE disc giving superior braking performance for everyday “Street” styled driving and are ideal for track days giving users that extra braking performance needed to win from the competition. For the Renault Clio RS III and Megane RS II the size has been upgraded to 330mm from 312mm and for the Renault Megane RS III to 350mm from 340mm OE discs.
