Another member had a great idea for a hose adaptor
He used a rubber plumbing adaptor from the hardware store. Great idea, I'm sure they make a Fernco adaptor that will give us the strength we need for hoses!

So, do you pick a random spot to drill the hole for the new ducts? Is there a particular spot? What type of fastener, metal screw is being used?

I drilled a hole where the duct hit the frame more or less see pic for exact location I used.
I just used some screws I had laying around. I think they are stainless or zinc coated..

I had my car on jackstands and then used a hydraulic jack to load the suspension, placed the duct where it looked like it would achieve ideal flow without being crushed by the upper A arms when the suspension was unloaded. It is pretty straight forward once you have the duct in your hand and the wheels off. I used a stainless sheetmetal screw in the frame after drilling a smaller pilot hole. I dabbed some silicone sealant on the threads of the screw before putting it into the frame, this should help seal everything up and prevent any corrosion.

Thanks for the pics and info Joe. Since my tires rubbed holes in my DRM ducts, this looks like a breeze and the smaller ducting will fit my spindle ducts better too. Do you think the holes from the DRM ducts in the liner will work for these new ducts?
Looks like my car will be ready in the near future for some fun. I'll keep you posted.
This is where I get my ducting from.

I would think the holes would work - if not the fender liner cuts like butter with a blade knife as you know. These ducts are a little different in that they meet with a duct under the bumper fs. straight ahead on the C5 but again, I think you can adapt something and for $11 if you screw them up who cares, try again! The hose mount is weak compared to DRM, the plastic is thin there. So you'll have to ge some sort of Fernco adapter to reinforce it like I posted a link to above. If I do it I'll let you know what I end up using but I'm not in a hurry, I don't have any track events planned until May at Sebring.

To C6400hp and Joe G: Thanks for all your info on the ducting and gurney lips. I installed the new z06 ducts on my c6 06 a6. I had to trim the fender liner to approximately 4 3/4" (slighter larger than the old factory c6 duct (4 1/4") I removed. My biggest problem was the output nozzel on the new z06 duct was approximately 1' away from the frame to mount it with screw bolt. Therefore, I had to cut to resulting 4 3/4 ' hole so that I could push the duct to the frame, also a part of the frame pushed down on the neck of the z06 duct. The overall result was that the output z06 nozzle aligned up on rotor inside surface straight on and the imput side of the z06 imput lip fit all but 5/16" over the bumper input cone nozze, resulting in no open gap. If you will make a template of approximately 4 3/4" in diameter this will simplify things quickly, place it on on the existing fender liner hole toward the frame and down toward the ground and cut these two sides only. Another words cut on the downward and inside areas only. This will still put pressure on the new duct because of the angle it travels to the frame. My second duct really went like a breeze, after the leaning curve on the first. I did not worry about the leaking around the duct going ito the fender, with the factory duct which rotates in and is pretty well sealed from tire splash. Trapped around the duct inlet area underneath the bumper was alot of dirt, so sealing would not help much. Again guys, thanks for your info and help. While at the dealer, I looked at the 07 c6 and z51's, they are now cutting off the small nozzel on the duct and is slmost flush with the wheel liner and having the total diameter open. This goes against all the hype about tuning the duct to have mimimum downward lift. They have talked about this in magazines articles, shown in wind tunnel tests on TV and brought up on show on Nurburgring test track testing. I guess they assume we won't be driving at the speeds BG is testing at. What are these guys at Bownling Green thinking about, a very short memory, note the small nozzel on the ducts we are installing. Have happy cruising, racing, and dragging.

Here's a thread on putting these on the C5 in case you missed it.

At the speeds that you will probably be driving, I am assuming that you will be driving way, way under 186 mph, you will probably not have a problem, never know with head winds, etc. I would think that the Z06 which is approximately 50lb lighter than a basic C6 and uses a 2 1/2 inch duct nozzle opening this size would also be a very close size (2 1/2") for the basic c6 except for the weight difference of the two cars, in fact because the basic C6 is slighty heavier, the hole could be minutely larger. I am assuming that the dynamics of the C6's is still the same from year to year and GM has not made a slight alteration that is not obvious to the eye. I would love to see test results of the new basic setup on the 07's, but I don't think GM will be doing this for us. It seems that GM is going back to the original opening size of the Z06 before they changed it at Nurenburgring Track test runs, they had handling problems there, before downsizing to 2 1/2". If course this didn't help brake cooling or fading, but it helped handling, can't have both without further modifications which other racers are doing. That's another area for the handling experts, the average guy is not into this and usually does not have the space to run all out unless he want tickets etc.

Joe, or anyone that can help:
I cannot seem to get the Z06 Duct to line up with the lower vent opening. I've cut the panel to fit the duct, but it seems to hang up on the upper edge...
Any help!

If you are talking about the Z06 hose matching up perfectly to the duct under the bumper, mine's not perfect either. Close but not 100%. Someone posted that they cut some more out of the bottom of the inner fender and they got it to line up but I didn't worry about it.

I did this to my C6 over the weekend.
The first one is 1/4 inch off so I use some aluinum tape to cover the gap.
There are tabs where the original duct goes in. I made the cuts using a utility knife. If you cut down and a littly I/B, you can get the Z06 duct to go over the existing plastic part in the fender. There are no gaps or tape.

I have a z51 07 Vette. I didn't have any fender liner or lower trim, so I ordered it before I ordered the ducts. It was around 200$ CAN for all 6 pieces of plastic.
I couldn't get the duct to fit like the OP has in his pic. I had to trim plastic on the fender liner to lower the hole, also make it bigger towards the inside of the car. I should have taken pics. Next time I take the front wheels off, I'll take pics and post. I also used one rivet to hold the front part of the duct on the bottom trim piece.
