Check out the Corvette OEM solution for a lower aero clearance but still have ramp clearance. An underside lower spoiler mounted deeper inboard from the very front. It diverts air from going under but still allows a deep entry ramp angle.

Looks exactly like garden edging!

The closer the dam gets to the front axle line, the lower it can go before hitting stuff. But I'd imagine it doesn't work at all if it's aft enough to be behind the front edge of the front tires.

Seems like the farther back it goes, the more it looks like a rough underside rather than an airdam. Still, you could make a really low one right back where that one is and test it out.

I'm struggling with this myself on the CR-V. The nose is very tapered, and there isn't the same kind of obvious place for an airdam like there is on most vehicles. The farthest-forward reasonable mounting point is just barely ahead of the front edge of the front tires.

There are times when a smooth bellypan is a better solution than an airdam. That is the direction I went with the Golf. The factory bumper scrapes often enough as it is.

Thanks COcyclist, for that advice. That is what I am thinking, too. I think I will go with a bellypan, and not an airdam. Everyone be on the lookout and please chime in when I get started on the bellypan. Hijack over.

Bill, if you were truly trying to hijack the thread, you would have yelled "Eco Akbar!!" first. I think that's in the rules somewhere.......

hi my first post . Q has any one used stiff brush material as an air dam material not 100% block but should be forgiving what do ya think

There was a long debate on mesh screen as a grill block on here that would probably be relevant. I assume you want to use this because you happen to already have some? Or maybe for flexibility? I think more solid materials would be better, probably.

From what I understand, smoother is better. Brushes are anything but smooth.

I'd recommend a belly pan and a custom aerodynamic topper. It can be made of plywood or coroplast if you like. Should go down at about a 15* angle.



Of course if you often haul tall loads that won't work too well.

When you make the belly pan, pull it straight forward, and wherever it ends up is how far down the air dam should be. Does that make sense?
