The Zimmermann Sport Brake Disc was developed as a result of experience of brake discs in series-production vehicles in connection with racing. The brake system is optimised by combining high-quality cast materials with a perforated braking surface.
Your advantages:
• Better wet braking performance by permanent expulsion of brake dust and water
• Sporty look
• Because of the anti-corrosion protection Coat Z better finish - especially of the hub and the outer diameter
• Noticeable improvement in the braking power of your car
• Prevention of brake fade
• Countersinking of holes doubles up as wear indicator
• 1:1 exchange of original disc possible
• No additional adaptions necessary
• Not subject to registration: general ABE certification supplied with 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.
