^^^AGREED!
Except that I just do not trust the quality of even the FIA Recaro shells given my
horrid past experiences with their (yes reclining) SPD seat, and their refusal to either warranty OR help me correct THEIR manufacturing problems with it.
The other factor which some might have to consider concerning aftermarket NON airbag equipped seats is that their state inspections might just fail them for no exploding whoopee cushions (as they might also for aftermarket racing
steering wheels),
even with the dash lights somehow cancelled out.
Of course, this does not matter for a pure track car, or in states with absolutely NO inspection.
But for a daily driven car, there could potentially be problems with insurance denying you medical coverage (they will absolutely
look for EVERY/ANY reason to deny claims) in a severe accident involving injuries to either party
