Re: RC et al: Question on 997 Safety features
The coupé features three-point seat belts on all seats (with belt latch tensioners and belt force limiters at the front) as well as a total of six airbags. These include two new two-stage full-size frontal airbags and the enhanced POSIP (Porsche Side Impact Protection) system now featuring a thorax airbag on the outer side of the front backrest and an unprecedented head airbag in the door. As long as it is not required, the head airbag remains concealed in the window sill at the bottom of the side window. In a collision from the side, the 8-litre head airbag is inflated to form a flat cushion ensuring optimum protection of the occupant's head both from an impact against the side window or another object and from glass splinters. The sensors serving to determine a side-on collision and, accordingly, to activate the side airbags are housed, first, in the airbag control unit in the centre console and, second, around the side-sills.
The new, two-stage frontal airbags are also activated by a new, enlarged sensor system. To determine the severity of an accident and the direction of impact, two sensors are fitted near the headlights in addition to the sensors in the airbag control unit. This ensures that a collision is detected much earlier and more precisely, particularly in the event of a complex collision such as an offset crash. The big advantage, of course, is that loads acting on the occupants in the event of a collision are further reduced, the driver and front passenger airbags being ignited a few milliseconds apart in the event a severe impact in order to "cushion" the occupants more softly. In minor accidents requiring activation of only the first airbag stage, the second stage is activated merely as a "discharge function" after 150 milliseconds. This has no effect on the occupants, but protects third parties seeking to save the occupants afterwards. Again in the interest of extra safety, the headrests on the front seats are 50 millimetres or 1.97" higher and closer to the occupant's head, thus once again improving head support in a collision.

Can anyone in this forum tell me if 997 has curtain side airbags for head protection or knee airbags?
Maybe this helps (official tech info from Porsche):
The revised Porsche Side Impact
Protection System (POSIP) includes
three airbags for each front seat.
In addition to the front airbag and the
head airbag integrated in the door-trim
panel, there is an additional thorax
airbag integrated in the outer side
piece of the front seats. The thorax
airbag has a volume of approx. 8 litres.
Re: RC et al: Question on 997 Safety features
Just discovered this thread. I didn't realize that there are three airbags, so the loss of the thorax airbag in the seats would be the only one you loose if you switch to racing shells. Since they have a greater stability and safety in side impacts, it all absolutely makes sense!

It ONLY would make sense if somebody really wants to seriously track race the 997 Carrera S, not just for fun.
The new adaptive sport seats can replace a racing shell pretty well, the only downside is weight. But I doubt that an amateur driver could ever take advantage of or feel a 20-30 kg weight difference.
