exactly that deago!
people who bitch about air ride stupid are either trolling (like dick wiggler), are not real car enthusiasts (childish) or are jealous that they can't afford it for themselves.
i know the last bit is true because i used to be like it myself. "haha bags are for fags coils are way better" but honestly i could just not afford it at the time. i see this often throughout the scene... hates going to hate and all of that.
having lived with them for a year i can honestly say bags are better than coilovers in my view for what i want out of my car.. a set of airlift performance struts will be more than a match for on anything this side of KW V3 / Bilstein ps8. the coilovers certainly won't ride as comfortably especialyl when at low heights - perhaps right at the very very top end of the coilover range (eg £4-5k coilover units, remote reserviour Ohlins units etc) you will find a minor improvement in handling but on the road and doing trackdays you won't notice this and any theoretical improvement will not be worth the exponetially increased cost.
you can lower your car to whatever height you want without needed to worry about catching your undertray or splitter or tricky driveways, as you can raise your car whenever you want
people make "performance builds" and some people make "show builds" for exhibitions, shows and what not.. there is no right or wrong way to modify a car. it's all a matter of personal preferences and your own vision and goals of what you want.
i don't personally like, for examples, vauxhalls - but i can all at the same time talk to an owner of a vauxhall and appreciate the work someone has done to his or her car. even if i don't approve of it in my head. you can step back and be like, you know mate that's a tidy car, not to my tastes but you've done it well. props to you.
this is where you seperate the true car enthusiasts who appreciate cars in general and the idiots who expect everyone to build a car how they would do it.
air is not for everyone and that's fine.
