Kit Contains:
Brake Disc 350MM 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. The rotor rings are bright zinc plated to help prevent unsightly corrosion

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 good 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 loosing the pedal due to boiling at the wrong time and making the day very expensive.

About Giro Slotted Brake Disc

Giro Slotted Brake Discs - High-Performance Braking Control & Heat Management

Giro slotted brake discs are engineered for enhanced braking performance, improved heat dissipation, and consistent pedal feel in both performance road and track-focused applications. Featuring precision-machined slots, these discs help clear brake gases, dust, and debris from the pad surface, maintaining optimal contact between pad and disc under demanding driving conditions.

Available from Design911, Giro slotted brake discs offer a balanced solution for drivers seeking improved braking response, reduced fade, and enhanced durability without compromising everyday drivability. Their advanced design supports confident braking during spirited road use and repeated high-load braking scenarios.

What Do Giro Slotted Brake Discs Do?

Giro slotted brake discs work alongside high-quality brake pads to deliver controlled and repeatable stopping power.

Core Functions:

  • Improve heat dissipation during heavy braking.
  • Remove brake gases and debris from the pad surface.
  • Maintain consistent pad contact and braking response.
  • Enhance wet-weather braking performance.
  • Reduce brake fade under repeated high-load use.

The slotted design ensures reliable braking performance across a wide range of driving conditions.

Why Do Brake Discs Wear or Fail?

Brake discs are subject to extreme mechanical and thermal stress over time.

Common Causes of Wear or Failure Include:

  • Thermal cycling leading to cracking or warping.
  • Surface wear from aggressive braking.
  • Heat build-up reducing braking efficiency.
  • Uneven pad deposits causing vibration or judder.
  • Extended service intervals beyond recommended limits.

As discs wear or degrade, braking consistency, pedal feel, and safety are reduced—making replacement essential.

Why Replace with Giro Slotted Brake Discs?

Upgrading to Giro slotted brake discs restores braking performance while enhancing heat management and durability.

Key Benefits:

  • Improved braking consistency and pedal feel.
  • Enhanced resistance to brake fade.
  • Better debris and gas evacuation.
  • Increased confidence during spirited and performance driving.
  • Suitable for performance road cars and track-day builds.

Replacing worn discs with Giro slotted discs ensures braking performance remains predictable and reliable under demanding conditions.

Highlights

  • Precision-machined slotted brake disc design.
  • Enhanced heat dissipation and braking stability.
  • Improved pad bite and consistent response.
  • Suitable for performance road and track use.
  • High-quality construction for long service life.
