First, let me just go off topic and vent for a sec.
Why oh why do people always equate power (400+hp, etc., etc...) with wings???!!!
Does anyone here ever watch go kart racing??? Many have less HP than your normal scooter, but they have wings. Why do people keep assocating the fact that to have good/proper aerodynmaics you "have" to have massive amounts of power? Good aerodynmics is just plain good old aerodynamics no matter how much power you got under you and no matter how big or small the object you're currently are holding on to dear life on!
Second, if you design a car with proper aerodynamics a wing is not necessary. Look at most super cars today (i.e. Ferrari's/Lambos/etc.). It's only when you don't do your proper due dilegence on design that you need to "add-on" something afterwards to compensate. Of course, I'm not referring to race cars that aspire to achieve the most downforce as humanly possible. And I know I know, these aren't supercars and we want them to be affordable. So I'll digress on this issue.
So for me, I'd just like a tasteful lip spoiler that actually does some good rather than bad. I'll even take it if it looks good and does nothing. I mean how much bad could a small lip spoilier do right?
My friend is an aerospace engineer and used to work at JPL in the wind tunnels designing Star Trek sh1t and he tells me that most aero stuff on cars do more damage than "real" good.
