Hey, just wondering if anyone out there has put air-bags in an EL sedan or something similar?

If so, have you had any problems with the install, or products?
Does anyone think there would be any major problems with putting them in, in the first place? cause i don't want to have to tub my car.
Does anyone know if they're legal in VIC?

I thought these might be a good idea for the car, apart from it sitting on the ground when i want it to, but when i'm towing, i can jack it up higher.

Thanks

Dave
