Ummmm.....airbags? 16 way power seats? lower ride height?
This is a supercar not a luxary sports sedan or sport truck. Airbags are cool, I love 'em but only on trucks. Plus the airbags would add unnecessary weight and probably couldn't handle the power and stress put on them. The crazy adjustable seats would only add weight slowing the car down. If the car were any lower it would probably be illegal to drive and you would get stuck left and right. You have to remember this is a supercar, meant to be driven hard(i.e. you need a very strong rigid suspension for good handling and control.) The big wheels would be cool but on exotic cars its hard to beat the factory look.
