Get bouncy air suspension. You can tell her you've got airbags (4 of them!), and more importantly, all you learnery friends think you're a pimp.
off an s15. I noticed one of these for sale off a z32 convertible, so you must be able to fit it with an adapter. wouldnt rely on airbag, so remove that
NOTE: do your research on this, it may or MAY NOT fit. it said it was for a z32 convertible however japanese to english translations aren't always helpful (nor the sellers description)
I've got a S15 wheel on my zed. Needed a bit of mucking about to get the horn to work, but was pretty easy.
Either your Mother has huge insight into your driving prowess, or she doesn't want to have you splashed across the otherwise pristine interior of your NA. Either way, you are not going to retro-fit airbags to a non airbag vehicle(and the level of additional engineering requirements needed for such an attempt would cost you more than the price of the car). PS, tell your Mother that there are thousands of cars out here on the roads THAT DO NOT HAVE AIRBAGS!!!!:br:
