I have taken my fog light out, not by choice but a stone hit it a cracked the whole lense.
All it does is make a fking anoying whistle at around 70mph which must be to do with the air flowing through the hole, Oh a a puddle of water that sit behind the hole left.
The only way to get any benefit is to cut the sh1t gaurds and use some flexi pipe to run directly to the Calipers. if you look at the set up you will see that the sh1t gaurds cover the whole area around the inner arch.
