A popular upgrade to the 996 Carrera 4S and Turbo is larger diameter rotors – swapping out stock 330 mm rotors to larger 350 mm rotors like those on the 997 Turbo. This change provides better braking action and feel.
Rennkit™ has the solution: Cal*Cool™ brake caliper coolers. A quick modification that allows excess heat to dissipate much faster. Conductive and convective heat transfer quickly dissipates brake caliper heat while driving. When parked, conductive and radiative heat transfer continue to effectively remove heat from hot calipers. Track tested – all 4 corners remained below 370F:

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.
