What Do EBC Ultimax Slotted Brake Discs Do?

EBC USR slotted discs are designed to improve braking efficiency and control.

Core Functions:

  • Promote effective brake pad degassing under heavy braking.
  • Maintain clean pad contact by clearing dust, dirt, water, and debris.
  • Improve heat dissipation and braking consistency.
  • Ensure smoother, more even brake pad wear.
  • Deliver stable, predictable braking feel under load.

For a performance SUV like the Macan, improved rotor efficiency directly translates into safer and more confident braking.

Why Upgrade to EBC Ultimax Slotted Discs?

Standard brake discs can struggle under repeated braking loads, especially on heavier vehicles.

Upgrade Advantages:

  • Refined USR slot design for effective degassing with minimal air noise.
  • Improved stopping power when paired with EBC Redstuff, Greenstuff, or Yellowstuff brake pads.
  • Reduced brake fade during spirited or high-load driving.
  • Smoother pad wear for extended component life.
  • Premium R90-approved grey iron construction for durability and compliance.

These discs are engineered as part of a fully matched brake system, ensuring balanced, reliable performance rather than relying on rotors alone.

Engineering & Quality Highlights

  • EBC Ultimax USR slotted rotor design
  • Precision machined in the UK and USA
  • Manufactured from premium R90-approved grey iron blanks
  • Slot pattern optimised for quiet operation
  • Extensive testing and rigorous quality control
  • Designed for rear axle fitment on Porsche 95B Macan

When combined with a high-friction EBC brake pad set, these discs deliver a noticeable improvement in braking confidence and longevity.

Key Benefits

  • Enhanced stopping power for heavy performance SUVs
  • Reduced brake fade and improved heat control
  • Quieter operation compared to aggressive slot designs
  • Longer brake pad and disc service life
  • Ideal for fast road and performance-focused driving

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.
