Been thinking about adding some rubber skirts on my Formula attaching them where the bottom rocker rivet locations and to the front air Damn, I*'m pretty sure many others have done this, (but couldn't find much when I searched.) I looked on ebay but nothing I found seemed to fit what I wanted. Wondering what you used / how thick should the rubber be to be effective, etc. Pics would be nice. Thanks.
Basically for the front yes, but bigger, those are properly only 2 - 2 1/2 inches. I would attach it in front to the air damn and to the metal strip that runs down the side of the car where the side rocker arms rivet to. I assume they need to be stiff enough to hold up against the air pressure but flexable enough to bend with the curve of the front and survive if they hit the ground during a bump.
The racers seem to like using thin sheet plastic for skirting. You can get that at some of the racing parts vendors. But I'm frugal, so I get sheets of plastic from McMaster-Carr industrial supply, and cut them to size.
On my Fiero's custom front end, I'm using a skirt made from 1/16" thick ABS plastic. If the skirt gets scraped-up or broken, I just cut another strip of plastic and tack it on. It also keeps the custom fiberglass work from getting torn up. I attached it using machine screws with nylock nuts. But you could probably get away with self-tapping screws.
