RST 4: Description: RST 4 is a semi metallic resin bonded material containing steel and acrylic fibers. This material has a medium friction level and high temperature resistance. Applications: Formula cars and open wheel racing. Rear axle material for Rally (tarmac and gravel) and for all front engine cars. Also used in NASCAR on long ovals. RSL 19: Description: RSL 19 is a low metallic resin bonded material containing steel and acrylic fibers. It maintains a constant friction level across a broad range of temperatures. The material features very good modulation and release characteristic. Applications: Rear axle usage in combination with RSL 1 and RSL 2 on the front axle in heavier cars (GT3/GTE). Front axle usage for lighter GT and Touring cars. RSL 29: Description: RSL 29 features very good modulation and release characteristics. It is a low metallic resin bonded material containing steel and acrylic fibers. The friction level of the material maintains constant at a low-medium level. Another advantage is the easy bedding in behavior. Applications: Very popular in club racing and track days. GT cars, Touring cars and prototype endurance racing.Due to excellent modulation characteristics also often used in sprint races.

Girodisc Ford GT350/GT350R Rear Rotor Rings Rear Fitment, Ford Shelby GT350/GT350R with Girodisc A2-162 rotors The Girodisc D1-162 is the direct replacement rotor rings for your Girodisc A2-162 brake rotor kit. This complete kit consists of two new discs (rotor rings) and all replacement hardware. You will re-use the Girodisc aluminum hats from your A2-162 kit and bring your braking feel back to new. Girodisc GT350 Rear Rotor Rings Details Manufacturer: Girodisc Manufacturer Part Number: D2-162 Surface: Slotted Material: Steel Intended for Street/Track Use: Yes For Use with Stock Calipers: Yes Rotor Construction: Vented Rotor Style: Slotted surface Rotor Material: Iron Rotor Finish: Black E-coat Quantity: Sold pair (one axle set) Sold/priced per pair of rings only (does not include center hat and does NOT fit OEM hats.) Girodisc Advantages Girodisc brake kits are seen at every track weekend on very exotic and extreme track cars. What made Girodisc owners leave their OEM rotors and upgrade to a 2 piece Girodisc kit? Less Rotating Mass via two-piece design Grade 12 floating hardware to allow the rotor to grow when heated Curved vane design creates a cooler rotor Significant cost reduction compared to OEM Girodisc Floating Rotor Rings Quality hi-carbon cast iron is the foundation of every Girodisc brake rotor. Every rotor ring is made carefully in house at the Girodisc factory in Washington state. The Girodisc rotor utilizes a curved vane design that was originally developed in racing to act as a centrifugal air pump to force cooling air from the center of the rotor ring to the outside. This principle is similar to what is know as a squirrel cage fan design. By having impellers (vanes) between the two rotor faces, the air is moved radially, from the center outward, changing the direction of the airflow and increasing velocity. This design is mechanically strong, reliable, and very effective. Girodisc Rotor Ring Hardware The Girodisc rotor ring and light-weight aluminum hat have a floating mount system, which utilizes 8 or 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for long-lasting corrosion resistance. These drive pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The drive 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 washers 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. Girodisc Rotor Ring Replacement Once the Girodisc system is in place, simply replace the cast iron rotor when needed. Your Girodisc replacement rotor rings come complete with two new rotor rings and all required floating rotor hardware. This is a very simple task that is quite fun. The aluminum rotor hat usually does not ever need replacement unless bent or damaged. If you damaged has reached your Girodisc hat, you likely have more than a few other things to replace also. The hat is rugged and overly strong.
