It's a magazine/book. There's too much to try to post everything. Here's the picture I said I would post for Old Tele man and thatguitarguy :



And here's the control logic :

I'd drop them when the vehicle exceeds 25mph, then retract when the speed is below 15mph.

I wonder how the mechanism would work in a mud/cold/snow/ice/salt environment? The area around the wheels gets the most snow/mud build up.

as far as tire fairings go i used to run something made out of linuleum

basically the shape was formed by the dimentions of the sheet and the way it was attached, but if it hit anything it would deform and take it's original shape. aerodynamically my version didn't work well, so i ended up taking it off but technically the system worked well, it didn't reveive more than a few scratches on the bottom

It is pretty inexpensive too.

Shop FLEXCO 48" x .333' Black Dahlia Wall Base at Lowes.com ( $ 2.48 a section )

The wall base looks 'factory' compared to the lawn edging I used to work with.Nice!

If the rocker panels weren't already as low as the belly of the vehicle,then doing skirts would get one even with contemporary technology.

A couple of questions:

Do you have any ideas about why it didn't work aerodynamically?

And, what is your belly pan made of? It's hard to tell in the photo, but it looks kinda like OSB?

Interesting detail on the Probe document.
"The use of a full length undercover body would incur unreasonable penalties in costs and weight and would not necessarily be the best solution"

Thanks Phil.

We sell that lawn edging that you guys use at Lowes, and the wall base is not only cheaper and more flexible, but also ( as you noticed ) has a "factory" look to it since it is actually made of rubber, versus shiny plastic.

Can you reword that Phil ?

Unless I'm mistaken, Phil is saying skirts should be as low as the lowest point under the car.
