I believe his name is Mark Stielow..... Was thinking that a piece of cardboard or thin insulation sheet could be cut to fit, then put some fiberglass cloth on it. use thin sheet metal in an L shape. Put some corresponding slits in to accomadate the L to make the runners fastened with some small button head fasteners. The same could be done in the front. If you wanted to do it yourself.

Ah, you mean Mark Stielow. The man has built some pretty awesome Camaros over the years. Have you seen his LS9, ZR1 brake equipped monster. It's pretty cool.

Depending on what class you are potentially going to run in the Silver State you can get by with some fairly basic pieces. I've never run the event but my '78 is stable at 140 mph with a fiberglass PC type airdam, an 80-82 rear bumper, lowered probably a little lower than it should be for the street and a fair amount of rake (245-50R15 in front and 295-50R15 in the back although I'm running 17's on it now). A splitter like BeeJay built would be excellent, especially for the forward supports to keep the front of it from bending down due to the air pressure on it.

Have you seen my diffuser? It's not perfect since it doesn't blend in the license plate holder like it should but it's a start.

So, what's a PC kit, and who has the best one?

This is the a fiberglass airdam http://www.ecklers.com/product.asp?p...9&dept_id=1353

You would have to come up with your own design for a spoiler on the rear.

Great thread, and a lot of interesting info to consider as I modify / improve my 71. I like the one piece idea, but the design is a little different than the original PC design. Does it make that much of a difference?

Has anyone mounted the 73 and later 3 Piece Pace Car spoiler to the 69~71?

The one piece dam burners posted does appear it may have a bit more of a leading edge extension than the PC, which should further improve the pressure differentials up front. I'm considering replacing my tired PC dam with one like it myself, perhaps in combination with a serious splitter, but want to see one up close to compare that and any differences in the rad air scoop. BTW, a rad extension should be installed behind it to keep air from escaping back beneath the car (a std OEM one should do).

FWIW, in my experience the original PC dam must be braced (BeeJay added a braced splitter to his) for any real prolonged speeds to keep it off the ground. The damage below isn't from parking curbs...
