jcc - nice work. Mind telling me what the bottom spoiler is adapted from? I have been going to use a 80's Ranger truck lower fascia as a buck to make a fiberglass mold from for my 66 Coronet, but yours looks like it's made from fiberglass?
Sorry about the big pic, don't know why it blows up like that using "properties" from the Moparts pic info...
I think I hear laughter in the background, but I don't remember, it has been a few years, and your are absolutely correct in that it is "adapted", if you look close, you can see 2 small eyebrow reliefs I had to fill in on the spoiler, maybe that will jog someones memory on what car I got from. Sorry guys. Please post if anybody knows, since I am certain I am going mangle it in my first big off track excursion, under braking

Ever notice how today's vehicles, especially trucks have a nose down rake to them? Same reasoning, cheap way to clean up the undercar airflow some.
I wouldn't necessarily consider a truck an accurate comparison considering they are designed to be carry a half ton load, at a minimum, and have rake for a differing reason than a car might use rake.
In any case, some of us old schoolers discovered the positive attributes of a 2-3* nose down rake back in about 1968 when mopar began teaching it on their Super Car Clinics and then later when it was published in the chassis manual.

Mine... 5" wide strips of 18ga. steel bolted to aluminum angle attached to the flat flange under the bumper and fenders. Really stuck this thing down at 140+.

Wonder if you noticed any "drag" increase, since you are running a "limited" class, I guess the only way to really tell in the field would be a coast down test. Every areo trick has a downside, just wondering how much in your case, and would agree whatever it was, its worth it. 
jcc, take your critical crap elsewhere.
The user stated that he liked the result at 140+ mph. If that makes him happy it doesn't matter what the coast down is.
He needed to limit air flow under the car at speed. He got it.
Now, kindly go away.

I'm pretty sure the OP can speak for himself.
Getting a little obsessed are we, or sorry, is that question hitting a little close to home?

Clay,
Here's a ground level shot of your car and spoiler as compared to what everyone else was running.

Did you also mount the tiny trunklip-spoiler that they also used on the Nascar-models (to counter backend lift I recall)?
Running fast in a straight line, the car may do OK. The rear lift problem did not show until they got to Daytona with the tighter corners. When they did their pre-season testing at the huge Goodyear oval in San Angelo TX, the car handled well without the spoiler. The turns were such a large radius that the problem had not yet become apparent.

Interesting, which is why i went with this - I wanted more function than looks - its a 67 camaro rear spoiler and would have been a perfect fit if it was about 1 1/2" - 2" longer

If you were looking for more width, a '69 Camaro spoiler is wider than a '67/8 one, incase you didn't know..
