I've been wanting to get gauges like that too....I have an 04' 3s 5-door...they airbags are NOT standard, but ARE an option....I have them in my car and would not recommend anyone w/ that option to do somethin glike this...I was in an accident in my friends Lexus which has similiar airbags and that whole piece pops down...I would think that the airbags would go off anyway as long as the gauges were'nt drilled or anything like that, BUT I'm almost positive it would interfere w/ the deploying of the bags....and when it comes to those things .01 of a second can make all the difference!!!
