I wonder how mine work 🤔

DarbyMX5, Why are you placing a NACA duct above the canard? I don't understand why you would want to bleed air pressure off the canard. Maybe you're more focused on getting it off the top of the tire?

I guess.....Brake ducting.

Got it. Just thought that would be grabbed from the front of the car where pressure is highest.

If that's what it is, this is not a great location for brake ducting for a number of reasons, first and foremost being the routing of the piping.

Hopefully that's not for the brakes. Actually, hopefully that's not for anything....

Its for tire cooling I believe

They connect to the brake bleeders to let fresh air into the system.

Could always string tuft test it with a GoPro on the driver's door. Maybe test out a small gurney flap attached to the ends of the fender area to exaggerate the pressure difference? Could try taping some cheap plastic L moulding along the edge and trimming it back until the desired effect is reached.

the naca ducts are for brake cooling, but thanks for your input.

That's better than for aero, but.... they're in pretty much the least effective place you could have possibly chosen. :(

Yup. Bad spot for brake ducts for a number of reasons. Nice workmanship though.

Yeah there is that. Execution of it all looks quite nice and tidy. Aesthetically pleasing.

As a part of the diet and aero upgrade regiment I put Creampuff on I decided to redo the lower section of the fender with a much deeper cut.
Lot's of sheet metal gone, small amount of it need to be put back in a new shape.
The taper that previously started about 3" inboard of the outside of the tire now clears the inside of the tire.
Pics coming soon.

Sorry Darby, that could have handled that better by all. Didn't mean to start a **** storm.

On a more constructive front it seems there's room for improvement there. Love what you did with the back of the fender though.

What size wheels are you running? Mind if I use this your fender design? Is this enough flare in the front for some 15x11 6UL's I'd like to do something like this paired with full over fender in the rear like the Carbonmiata ones

Nice execution on the fenders Darby. I would assume once you cut the fender a 15x11 would clear no problem, just pull up lol

Bringing this back up. Has there been any meaningful scientific conclusion on the most effective way to vent the fenders? It looks like what Moti and Ryan have done is probably the most effective but also the most extreme. Has there been proven advantages?
