I don't think you're getting what I was saying. I was saying the idea of a body kit decreasing lift or lowering the Cd is invalid since it doesn't work. And again, aerodynamics come into play below highway speeds. That means at 40-50mph, aerodynamics are affecting your car.

As far as them being for looks, that's what probably 90% of the people that have them bought them for (the other 10% being practical applications like running brake cooling ducts or having a giant FMIC).

 

i understand that but u just said what i was trying to say, 90% of people just get them for looks, they get the cheap fiberglass ones with chicken wire all thru them and then they tell their friends it helps them with aerodynamics. a stock bumper will not hold you back in a race, meaning a bodykit isnt going to really give you any advantages with aerodynamics. it might help bring air into your engine or brakes and cool you down but it really has no effects otherwise unless you get one made specificly for that. 99% of the body kits on the market are for looks and nothing else.
