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.

About SPORTS Brake Disc

Experience race-inspired stopping power with Porsche sports brake discs from Design911. Designed for performance driving, these upgraded brake rotors provide greater heat dissipation, improved bite, and enhanced fade resistance, ensuring confidence under even the most demanding conditions.

What They Are & What They Do
Sports brake discs (or rotors) are precision-engineered components that work with brake pads to generate friction and stop the car effectively. Unlike standard discs, sports variants are often drilled, grooved, or slotted, helping to vent heat and gases, improve braking response, and maintain consistent performance during high-speed or repeated stops.

Why They Fail
Over time, brake discs wear down from heat cycles, friction, and corrosion. Common signs of failure include scoring, warping, cracking, or vibration during braking. Track use or aggressive driving can accelerate wear, while low-quality discs may develop hotspots and fade under stress.

Why They Should Be Replaced
Replacing worn or damaged brake discs restores optimal braking efficiency, pedal feel, and vehicle control. New sports discs not only improve performance and safety but also extend pad life and reduce fade, ensuring Porsche’s legendary stopping precision. Design911 offers genuine Porsche discs for factory performance and aftermarket upgrades for enhanced durability and responsiveness.

Whether you’re restoring a classic 911 or tuning a Cayman or Taycan for track use, our range of sports discs combines precision, reliability, and performance to keep your Porsche braking like new.

Aftermarket Performance Brake Discs
High-quality aftermarket discs featuring slotted or drilled designs for superior airflow, reduced fade, and consistent friction performance.

Front Sports Brake Discs
Heavy-duty front rotors built to handle intense braking loads, offering maximum stopping power and stability under pressure.

Rear Sports Brake Discs
Rear discs designed for balanced braking and improved heat management, ensuring control and composure under repeated deceleration.

Drilled & Grooved Brake Rotors
Advanced rotors engineered to dissipate heat, clean brake pads, and deliver responsive braking for track and fast-road applications.

Motorsport & Track Brake Discs
Race-grade rotors made from high-carbon or composite materials, offering unmatched durability and thermal control for competition use.

Porsche Brake Disc Upgrades: Venting, Drilling, and Grooving Explained
