Need Pics of Urethane Air Damn Brace

[AlbatrossCafe]

I have seen that people put some kind of bracing behind their urethane air dams on their cars so that they don't flex at high speeds, often for pretty cheap.

Anyone have any pics of what this looks like? I am not sure how to start or where to attach it to. I could figure it out from a pic of the setup.

I rigged up this splitter  brace to keep the air dam stiff, those rectangular pieces grab onto the inside lip of the air dam.  It works pretty well but I didn't get a piece of aluminum wide enough to cover the full width so I will probably build another one. Hope this helps.

I put the bottom metal lip behind mine.  '77 280

Spoiler on top, spoiler lip (scratched up), belly pan.  Picture taken from the ground up.  Stopped my high speed flexing, vibrating.

Those pics help, thanks.

Where are you guys sourcing your metal? Did you just go to the hardware store and buy big square pieces?

My stuff was OE.  Welding shops around here will sale sheets.

I go to place down in the industrial area that is sort of a metal supermarket, I would think most cities have something similar. That piece of aluminum sheet was $35. Hardware stores will charge you 4 x what you will pay at a metal shop.
