Company verbage & information:
GiroDisc is a brake technology company that is dedicated to the development and manufacturing of high quality brake components and brake systems. GiroDisc products are designed and engineered for both street and track applications with a comprehensive product line of two-piece
floating rotors that are designed to be a direct replacement for the factory rotors.
The two-piece floating rotor will improve braking performance, reduce unsprung weight and utilizes the factory calipers and e-brake.
Unlike many “big brake” packages on the market, GiroDisc rotors also retain the factory brake bias and outstanding pedal feel. High quality construction and premium grade materials provide improved wear, increased rotor life, minimized coning and greater cooling efficiency.
Note how the slotting is *properly* done with tapered ends and plenty of edge margin.
These represent good value, readily available replacement parts, and amongst the highest quality in the industry.

Girodisc announces a brand new rotor casting that will be used on most applications with an outside diameter between 345mm and 355mm
• Braking Performance: The forty-eight directionally curved vanes act as a centrifugal air pump and actively move cooling air through the rotor as it rotates, helping to shed heat quick 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 rotors use only the highest quality materials and components. The rotors are high carbon content iron for long wear and stable thermal performance. We have developed alloy combinations that are consistently outperforming anything we’ve had in the past. This is proven on both the brake dyno and the race track. We have worked closely with American foundries and testing facilities to help us design our castings and tooling to make the best possible product. This is a commitment to our customer and our country’s economy. All our iron is poured in the US.
The center hat section is aircraft grade 6061 billet aluminum with a charcoal grey color Military spec type II anodized finish. We use only American made aluminum from Kaiser, Alcoa and SAPA. The disc hardware consists of cadmium plated high strength alloy steel drive bushings which take the load from braking actions while maintaining the float between the hat and disc. Girodisc manufactures all these components in-house to our own specifications. Disc machining, hat machining and pin machining all happens at our facility in Bellingham, WA.

To clarify - YES these DO have rear parking rake provisions unlike many others. Ready to build and ship from right here in Washington State :-)
