NEW 360-430 ROTOR DESIGN FROM GIRODISC

We have released an updated and optimized design for the F360-F430 2pc rotor.

The new design opens the rotor annulus a bit from the previous generation so that the bell is a bit larger in diameter. This means there is a little less excess iron and a bit more aluminum than before.

The mount flanges of the rotor have been thickened, and there is now a small register lip on the inside of the bell mount flange to limit bell/rotor movement as a failsafe. Float is the same as before both axially and radially.

For those that have the first release rotors, you will be upgraded to the new hats when you order new replacement rotor rings. We will eventually have all customers on this new design.

The logoing shown is prototype, tell us what you think, is 5 Girodisc logos too much? (we are proud, can you tell?)

Get in touch with Martin at the shop with any questions and orders.

Cheers gang,
Eric

In simple terms here are the most important factors -


1. PERFORMANCE - Weighs less and sheds heat better than OE (weight is important!)
2. COSTS LESS THAN THE 1PC OE ROTOR FROM THE DEALER!
3. Only the iron rotor needs replacing when it is worn down to min thickness. This costs even less again!



A more comprehensive explanation:

The Girodisc brake rotor system is a direct replacement for the OE F360 front and rear, and provides significant weight, handling, and brake fade-resistance performance benefits. The rotor set is compatible with the OE brake pads and will also tolerate the higher heat and wear levels of performance and racing spec pads. The Girodisc system provides an economical and performance enhancing replacement solution for vehicles which will see track use. Additional product benefits of the Girodisc lightweight brake rotor system include:

• Weight Savings: The Girodisc brake system weigh in at 9.2 lb less than the OE system. 2.3 lb Lbs per disc is removed in front and 2.3 lbs from each rear disc. The Girodisc front discs offer a 14.5 % improvement in surface area-to-weight for the front and rear rotor. The light weight disc decreases the rotational inertia of the braking system and reduces unsprung mass.

• 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. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise springs which allow the rotor to grow but eliminate rattle. This float also allows the rotor to self center between the pads. Thirty-two directionally curved vanes in the rotor 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.

• 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, with zinc plating for corrosion resistance. The top hat section is aircraft 6061 T-6 billet aluminum with a gun-metal color anodized finish. The disc hardware consists of 10 cadmium plated alloy steel drive bushings which take the load from braking actions while maintaining the float between the hat and disc. Grade 12 cap screws with spring washers allow for float under braking while maintaining a rattle-free assembly while cold.

Also below are pics of the system on cars - sorry fasthound no pics with a 430 yet. As for the logoing, you can expect something more in line with the first generation, and a bit more subtle than the prototype.

Eric
