brake vents on with enclosed bodywork
hi all. Just scheming for the next build here. I was wondering if the vents you see on many LMP style cars, in front and behind of the front wheels,
are actually required for ventilation of the front brakes, or are they more aesthetic?
i was considering the possibility of having no hole in front, but a small hole behind, to try to suck air out without specifically ducting any at the
discs. The aim of this being twofold, to leave the front more aerodynamic and to slightly reduce the pressure under the front end to keep it down
better.
any thoughts? obviously none of us have wind tunnels, so educated guesses will do!

I think it depends on the type of brakes, loadings etc.
I saw this photo of the Apollo Gumpert thing. Hopefully you can make out the shape of the nose from the massive splitter. This appears to have a
radiator at each side and a void in the middle. Behind that void is are a couple of 4 or 5" diameter hoses or ducts running straight into the
brakes themselves.

I'm guessing this is a big buck brake set up, but as the car has a design maximuum top speed of 224mph, you'd want to have confidence in
them?

P.S. That splitter looks to be about an inch thick in other shots, but helps generate 600kg of downforce on the front axle alone.

I'm fairly sure the vents at the rear of the front arches are to relieve the high pressure area under the arch, therefore making the whole car a
little more aerodynamic (in theory)

When thinking outside the box doesn't work any more, it's time to build a new box

i think the solution is small discrete piping to the front and small vents at the rear.  cheers for the opinions guys
