Gents,
With the stage 3 Aero am I supposed to get a front air dam. If you look on the Chev web site under Z06 build and click through the different areo packages available you see an air dam. Thanks in Advance!

Z51 and Z06 doesn't get the air dam. I believe Z07 doesn't get it either.

No, that is not the case. All C7s have an air dam. What the Z06 and Z51-equipped Stingrays do not have is the center section. They still get the side pieces of the air dam.
Harlan Charles explained that the center section was removed to improve downforce and airflow on cars with the larger spoilers.
My 15 A8 Z06 stage 1 also had the center air dam too when I picked it up. After reading a thread or two here I removed it. So far So good, no problems what so ever.
PS: Hell I even removed the front Stage 1 splitter too because it would hit my driveway entrance. Seen no problems with removing that either. IMO it now has an all business "get it done" look which is leaner & more muscular. No corny double row of shark teeth here.

The Stage 2/3 undertray does not have provisions for the center air damn. On the Stage 1 cars, the air damn attaches to the filler panel that covers the opening in front of and below the radiator. The Stage 2/3 undertray covers this and there are no holes to mount the center air damn.
If it didn't come with it from the OEM, why would you want to add it?

I wonder if the A8 Z06 gets the center section to direct more air to the aux trans cooler up front...? Seems to me GM wouldn't ship a center section with the car if they didn't want it on for some reason. Or for that matter, adding a center section if it didn't come with the car. All front aero bits are installed at PDI.
There is no standard 'kit' shipped with all cars for which pieces need to be left off based on RPO at PDI. Extra cost, and extra smarts required...

Only the Stage 1 cars get the center air damn. And it can't direct any air to the second transmission cooler because that cooler is completely covered from underneath by a tray.
I'm not sure what benefit the center air damn provides.

Ah. Didn't know it was covered underneath. I figured it looked like the horizontal coolers the centri kits come with that vent straight down. Where does the flow through the front trans cooler get vented? Further aft?
From my albeit limited aero knowledge, a full front air dam helps decrease airflow under the car by deflecting it outward thereby reducing turbulence and reducing drag and/or managing lift. The extreme of air dams being like what you see on NASCAR. Undertrays/belly pans are a whole different matter.
When the Z51 vs. standard air dams were being discussed, the conclusion seemed to be that the center section was left off Z51 to allow more flow for the control arm mounted front brake scoops (not present on the standard car) as well as aid the upgrade rear diff cooler. The side pieces are there to deflect air around the tires more smoothly.

Nope...it's covered on the bottom side of the trans cooler. This area is closed off on the M7 cars too. I suppose that they wanted to trap air and create a high pressure area in front of the radiator. Obviously this isn't a sealed and air tight area, so air can bleed out behind the undertray.
Looking that this area closely this week while working on the car, there are several different ideas we have for ducting air to the PS motor and oil cooler.

Just to be clear, the A8 Stage 1 is "completely" covered underneath in the center area from the front to the engine cradle. At least mine was along with that center front air damn which I removed.
The only reason that I could think of for that center air damn on the Stage 1 car is to cut down on lift, which due to the different set-up on the Stage 2/3 cars was not needed with their higher down force and "drag".

It was mainly taken off for the REAR brake scoops. Leaving the center dam off Z51 models allows air to travel under the car to reach the rear brake scoops. It does provide some air to the front underbody brake deflectors, but those are open channels so the effect would not be as pronounced.
