The problem of brake fluid boiling is simply traced to heat transferring from the rotors and pads directly into the fluid through the caliper pistons. When brake fluid boils, it releases air that is normally part of the molecular structure of the fluid. This air is compressible of course, and the brake pedal goes to the floor instead of moving the caliper pistons. Production cars tend to suffer from this on track days more as they don't usually have the extensive cooling duct and exotic brake materials as true racing cars. True racing only brake calipers generally come with titanium caliper pistons for one reason. Titanium as a material has low thermal conductivity. This means that it is very bad at transferring heat, which is fantastic if you are trying to keep your fluid cool.
The Girodisc solution to help prevent fluid boiling is to use a thin titanium shim placed between the pad back and the pistons, to keep the braking heat from transferring into the pistons and fluid. Here is a comparison of materials and their relative thermal conductivity ratings:
Titanium 6AL-4V 6.7 W/mk
Steel 52 W/mk
Aluminum 130 W/mk
You can see that Titanium will transfer far less heat than steel and especially aluminum. For cars that are going to see hard or multiple track days, these shims are cheap protection from losing the pedal due to boiling at the wrong time and making the day very expensive.
Water jet cut to exact size, no cutting, grinding, or swearing involved.
Price is per axle (four pieces)

Kit Contains:
Brake Disc 380MM complete with centre bell.
Brake Disc Type: 2-Piece Slotted
The Girodisc brake rotor is a direct replacement for the OE discs, and provides significant performance benefits. The rotors are compatible with any of the current pads typically used with these cars.
Additional information:
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.
More heat sink without a weight penalty: The Girodisc disc set weights in a little lighter than the OE system but with an important advantage. The rotors have grown in diameter. This means that weight has been transferred from the center hat were it does nothing to the outer diameter where it is actively absorbing and dispersing heat.
High Quality Materials: The Girodisc system uses 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 machined from billet aluminum with an attractive anodized finish.
