Do body kits improve aerodynamics of a car, or are they only just to enhance the appearance? I cant imagine that too many body kit companies actually test their kits in a wind tunnel so this is why Im wondering. Thanks.

 

I dont think they do. It wold cost too much for companies to do it.

 

At legal speeds, no. For F1 cars, even NASnotaCAR, yes. Although I don't know that NASnotaCAR does wind tunnel testing. F1 definitely does.

 

Only company I am aware of that has done windtunnel testings before were Veilside.



Other bodykits are simply for looks
