Not suitable for PCCB (Porsche Ceramic Composite Brake) conversions.
Designed as a direct replacement for vehicles equipped with 350mm steel brake discs, including centre-lock wheel configurations.

Each assembly consists of a precision-machined aluminium hat paired with a high-carbon cast iron rotor ring, providing optimal heat management and reduced unsprung weight.

What This Brake Disc Kit Does

Brake discs convert kinetic energy into heat during braking. This upgraded system improves heat dissipation and braking consistency under load.

It helps:

• Improve braking performance and consistency
• Enhance heat dissipation during repeated braking
• Reduce brake fade under high temperatures
• Improve pedal feel and braking response
• Increase durability compared to standard discs

Advanced Two-Piece Floating Design

The floating disc construction allows the rotor ring to expand independently from the hat under heat, reducing stress and preventing distortion.

Key benefits include:

• Reduced risk of warping under heavy braking
• Improved thermal stability
• Minimized vibration and brake judder
• Enhanced performance during repeated braking cycles

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
