Thanks very much. That is very helpful. I've not seen the Recaro seat option added to the VO before.
I understand what most of the items you list should be set to 'not-active'. The side airbags, are these the airbags in the seats or door frame?
If they are the seat airbags, makes sense to use 'not-active' as airbags are not present in motorsport seats.
Also do you know what happens to the passenger airbag above the glove box? Will that still fire at all times in a suitably fierce accident or is the seat occupancy effectively telling the car that it is unoccupied?
