... Louvers are used over the fenders of sportscars to relive high pressure that builds up from the fast spinning tire, and from the complex interaction of air flowing in, out, and through the wheel arch.
The general rule is the more air you can extract from the wheel well, the better. On street courses, prototype teams will usually sport the biggest, longest, and most aggressive forms of louvers to vent air and create downforce. Another aspect of most louvers is their taller height (to give air a chimney to flow out from) that extra height adds more volume to the outer profile of the carmaking a bigger hole for the passing air to go over and thus reducing straightline speed. ...
Sooo, I'm vending my fenders. Thought I would share with the class....
I'm not done, of course. Trying to decide between louver vents, mesh, dimpled holes or what... any ideas?
