I use the ZL1 vent on mine as it looks more "factory" hahah. Never had an issue with temps beyond a normal vette really but on Drag Week anything you can do to prevent stuff is a smart choice. I can honestly say that at highway speeds the vent alone was worth a solid 10 degree temp reduction during the heat of the day and more during the night time drives. Some evening drives it was down as low as 167 degrees, and that's after hours of continuous driving while towing its own trailer that weighs 500lbs loaded.

I just want to thank vettedean for this post. Until I read it I had no idea that my car was missing the two end pieces of the air dam. I will be installing them soon or maybe a whole new assembly. Thanks again.

It doesn't really contour to the hood, but it's got a vertical bit that fills in that area. It looks fine, but it will collect water if it rains.

ok that's what I was wondering about the gap. Does the water have any bad effects out of the center vent because I have a Airaid air filter on it? Ty for making time for me, to answer my questions.

I drive mine in rain all the time, and I've got an open element filter...I think mine is a K&N. I've had no issues. I think the vent is actually behind the air intake anyway.

Do you have any more photos of this splitter and air dam setup?
It stops excessive air from building up in the wheel wells, which not only causes lift, but decreases how much air you can get in to cool the brakes (only a problem on the track). It also stops high velocity, turbulent air coming in under the car from continuing back. You need air underneath to feed the radiator, but not anywhere else; you want as little high velocity air under the car as possible. Also, tires are like a brick wall when they computate drag; best to direct air around them, than to leave them to open frontal air flow.
The front end on the C5 is a tricky one since it bottom feeds the radiator, so you will always have a light front end at real high speeds in stock trim. If you have a vented hood, it greatly reduces that effect. On C5 track cars, it is common to completely cap off the bottom of the car, and turn it into a front breather. Then use a big splitter to get good front downforce, and vent the radiator out the hood. Often times (rules allowing) you see track cars vent their front fenders through the hood as well (important if you have a powerful brake cooling system for track use).
The hood on my car will balloon up so severely at 160mph, you could slide your whole hand between it and the fender. As soon as I cut vents in my hood, I picked up not only high speed stability, but about 20mph in top speed!
At the end of the day, they are good for a street car. Do you NEED them? No. Do they benefit the car in aerodynamically stock trim? Yes.
