looking at splitters and diffusers I had to questions on the new CAM rules about this:

1) It says that a Front splitter, air dam, and/or spoiler may be added below the bumper, but must not extend past the perimeter of the original body excluding non-integral bumpers. Now does that mean it cannot extend past the front bumper of the car, or the body the front bumper is attached to?

2) what are the rules on rear diffusers? I don't see any rules on this so is it open?

Lets see some pics of your Front splitters and rear diffusers!

I was looking into these rules because I was thinking about making some carbon fiber front spoilers and rear diffusers for the Dart. It would probably be more for show than go. As far as I can tell, if the car has a bolt-on bumper (like the Dart) the front spoiler can pass in front of the car since the bumper isn't integrated to the body. The "non-integrated bumper" rule I think follows more along the lines of the newer Mustangs and Camaros. Their front splitters can be pretty gnarly.

I believe the diffuser falls underneath the rear spoiler rule since it's technically not a wing. So it could go as far back as 8" behind the bumper. Or if you don't even consider it a spoiler, it's technically open to any modifications... that is till next year when SCCA throws a rule on it.

It can't go past the front bumper.

What he said. That's still way more than you need. I'm straight down off the valance and can hang 6" of splitter out if I wanted and still not be at the end of the bumper.

thought of that, but then again a splitter was never part of an original feature but its allowed

The diffuser point you make is valid IMO.
