Girodisc
Girodisc is an American maker of two-piece floating brake discs, and those discs make up most of its range here. Each disc pairs an aluminium hat with a separate iron friction ring joined by floating bobbins. Both complete assemblies and replacement rings are listed, so a worn ring can be renewed without buying a new hat. The rings are curved-slot, vented and sold as left or right parts.
Around the discs sit caliper rebuild and dust boot kits, drive pin and caliper stud kits, titanium backing plates and GP-series pads. GP10 is listed as a sport pad, and GP30, GP35 and GP40 as race compounds.
The listings concentrate on high-performance cars. Porsche leads, with the 911 from the 996 to the 992, the Cayman and the Boxster. Chevrolet, Audi, Ferrari, Lamborghini and Mercedes-Benz follow, with Ford, BMW, McLaren and Subaru among the others.
Most disc ranges on TrackToolFactory are one-piece. Girodisc is the main source here for a two-piece floating disc sold to replace the existing disc, rather than as part of a big brake kit.

Description
This indispensable tool is designed for use by race teams and enthusiasts alike who have high performance 4 and 6 piston calipers. The spreader is designed to spread the pads and then the pistons in 4 and 6 piston calipers to facilitate quick replacement of pads and rotors in a shop or racing environment. The Spreader was designed around the popular Porsche 4 piston and GT2/3 6 piston calipers as well as most 4 piston Brembo, AP, Alcon, and other performance calipers in racing and road use. To help fit in any caliper, the amount of throw is adjustable through three settings of the outside plate. Insert the spreading plates one way for wider 6 piston calipers, and then turn the unit 90 degrees and use the plate sides for 4 piston calipers. The tool is made from steel and is powder coated for durability. The slider is cadmium plated. The pivot bushings are all made from nylon and will ensure smooth action.
