Fitted as standard on the 911 GT3 models are Bi-Xenon™ headlights with dynamic range control. These are approximately twice as bright as conventional halogen lights. With low or high beam, the lights are stronger and more uniform, helping to minimize driver fatigue. A headlight cleaning system is built in.
For occasional use on the racetrack, lightweight halogen headlights without integrated cleaning or range control are available as a no-cost option.
The front light units incorporate the direction indicators, the LED daytime running lights and position lights, which provide outstanding visibility and create an imposing look.
LEDs are also used for the rear direction indicators, taillights and brake lights, the additional brake light in the rear lid and the rear fog lights. These provide better illumination and respond more quickly to driver input so that following traffic is alerted earlier. They are energy efficient, eco-friendly and have a longer service life than conventional bulbs – as well as an unmistakable design, day or night.
Dynamic cornering lights
Available as an option, dynamic cornering lights provide particularly effective illumination of the road. Sensors permanently monitor the speed, lateral acceleration and steering angle and, from these variables, calculate the course of the curve.
This determines the angle of the dynamic cornering lights, with low beams able to swivel outwards up to 15 degrees. So the course of the road and obstacles can be identified much sooner, particularly during corners.
Porsche Ceramic Composite Brakes (PCCB)
Optional for the 911 GT3 and the new 911 GT3 RS is brake technology that has already had to withstand the harshest requirements of motorsport: the Porsche Ceramic Composite Brake (PCCB).
To enhance braking performance, the ceramic composite brake discs in PCCB have a diameter of 15 inches at the front and 13.8 inches at the back. They are made from a specially treated carbon-fiber compound that is silicated in a high-vacuum process at around 3,092 °F. The resulting brake discs are much harder and more resistant to heat than standard discs.
PCCB is characterized by its low thermal expansion which prevents deformation under heavy braking. Furthermore, the ceramic brake discs are totally resistant to corrosion and offer better noisedamping properties.
The use of six-piston aluminum monobloc brake calipers at the front and four-piston units at the rear helps to ensure extremely high brake forces which, crucially, are exceptionally consistent. The pedal response is fast and precise with only moderate input required.
All the prerequisites are there for a short braking distance, even in the toughest conditions. Moreover, safety when braking from high speeds is increased thanks to excellent fade resistance of the PCCB.
The key advantage of PCCB is the extremely low weight of the brake discs which are about 50 % lighter than standard discs of similar design and size. In addition, the monobloc calipers for the 911 GT3 models on the front and rear axle are made from aluminum, saving around 10.5 lb per vehicle compared to standard calipers. These factors not only have an impact on performance and fuel consumption, but also reduce unsprung and rotating masses.
The result: better road-holding and increased comfort, especially on uneven roads, as well as greater agility and even better handling.
Please note that circuit racing or other forms of performance driving can significantly reduce the service life of even the most durable brake pads and discs. As with conventional highperformance braking systems, we recommend that all brake components be professionally inspected and replaced where necessary after every track event.
Porsche brakes are renowned for their high level of efficiency. They set the benchmark for deceleration and stability and are designed for extreme conditions.
The new 911 GT3 RS and the 911 GT3 have a particularly powerful yet lightweight braking system with a specially adapted booster. The red-painted six-piston aluminum monobloc calipers on the front axle and the four-piston units at the rear provide a high level of rigidity and a consistent bite point, even under heavy braking.
The composite brake discs are large, with a diameter of 15 inches at the front and 13.8 inches at the back. Thanks to their two-piece design with newly developed standard brake discs and aluminum monobloc calipers, the weight is reduced and therefore the unsprung and rotating masses are also reduced.
They are cross-drilled and internally vented for optimum performance in the wet.
Brake spoiler elements on the front axle, plus the new brake ducts on the rear ensure that the braking system is effectively ventilated.
Also designed for high performance is the four-channel anti-lock braking system (ABS 8.0) which is fast and precise, helping to ensure consistent deceleration and excellent overall brake performance.
Both full-size airbags inflate in two stages, depending on the severity of the impact. In a lowspeed collision, the airbag is only partially inflated, thereby reducing occupant discomfort.
Porsche Side Impact Protection System (POSIP)
POSIP comes as standard and consists of side impact protection beams in each of the doors and side head airbags for each front seat. In addition, thorax airbags are located in the sides of the sport seats and head airbags in the door panels. With a volume of around eight liters each, these provide a high level of protection in side impacts. Additional safety features are the headrests integrated in the backrest, a safety steering column, three-point seat belts with height adjustment, seat belt pretensioners and force limiters and energy-absorbing elements in the dashboard.
