The Girodisc brake rotor system is a direct replacement for cars equipped with the Lotus Sport/AP calipers. They provide significant cost, weight, and brake fade-resistance performance benefits. The rotors are compatible with any of the current pads typically in use. Additional product benefits of the Girodisc brake rotor system include:
:: Weight Savings :: The Girodisc disc set weights in at 10 lb less than the OE system. More than 2 Lbs per disc is removed in the front, and the rear is 3 lbs lighter than the OE disc. The Girodisc front discs offer a 15% improvement in surface area-to-weight for the rotor. The Girodisc rear discs offer a decreased pad annulus more in line with the actual rear pad swept area. The light weight disc decreases the rotational inertia of the braking system and reduces unsprung mass. The Girodisc lightweight discs help improve acceleration and require less energy to be dissipated during deceleration.
:: Braking Performance :: The internal directionally curved vanes act as a centrifugal air pump and actively move cooling air through the rotor as it rotates, helping to shed heat quickly and reduce brake pad fading. The discs are also slotted, allowing a maximized contact at the interface between pad and disc as the edges of the slots continuously clean and refresh the pad surface. No more cracked rotors from drillings. The floating mount design allows the rotor to expand uniformly while in use giving consistent pedal feel and predictable results. These rotors will provide lap after lap of trouble free, confidence inspiring performance.
:: High Quality Materials :: The Girodisc lightweight discs use 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 2024 billet aluminum with a grey color Military spec hard anodized finish. The disc hardware consists of 10 cadmium plated high strength alloy steel drive bushings which take the load from braking actions while maintaining the float between the hat and disc. Titanium pad backing plates are available to further block heat transfer to the caliper and fluid.
Keep in mind that hats, just like rotors and pads, are wear items. Inspect the hats for any sign of damage or cracking when replacing the rotors and pay particular attention to the rotor mounting holes
