Giro Discs – What Are The Benefits?
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.
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 allow for axial and radial float.
More Heat Sink Without A Weight Penalty
The Girodisc disc set weighs 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 centre hat where it effectively 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.
For instance, the rotors are high carbon content iron for long wear and stable thermal performance, while the top hat section is machined from billet aluminium with an attractive anodized finish. The rotor rings are even zinc plated to help prevent unsightly corrosion
