The middle section helps with cooling for the base car (not widebody). The outer pieces help with directing air to the brakes on all models.

I'd leave them all on and let it scrape...its no big deal. I don't know why everyone gets so worked up over that thing scraping and make a thread about it every week...http://www.vwvortex.com/Anthony/Smilies/facepalm.gif

the scraping got on my nerves and the outer ones kept coming apart at the seam and looked like it had been wrecked..so i took them off...cooling pblms? have not noticed any difference in either brake performance or engine coolant temps...

Grand Sport, Z06 and ZR1 are 100% front feeders as the opening under the nose is closed off. The air dam is there for aerodynamics. It minimizes the amount of air going under the car and hitting the wide front tires. It also helps direct air into the front brake ducts located in front of it.

:iagree:That is why GM added them,but they don't do much good, as said in car & driver mag.I removed my 2 yrs ago with no change in temp.The end ones are easy to remove,but the center one Not so easy"

:iagree:


The air dam does not add frontal down force - it helps reduce overall drag for the car by preventing more air from spilling under. However it does help with lift on the rear because there is that much less air traveling under the rear end. This has been tested by katech in a windtunnel, and the information is available online.

If you didnt buy the corvette to drive fast, then the only reason to keep the air dam is to warn you before you take out your bumper or radiator support.

:iagree:^^ fact ^^ :iagree:

HeY I'm all for letting it scrape

However, this is deforming it to point where it sperates from pin holding it to center piece

It thats ok and it wont tear loose I will let it go and swap out like wiper inserts every
year.

Just want to make sure its secured and can take a beating

Ive had to replace those stupid tabs numerous times, but the airdam has stayed fine.

I did recently switch to these (available at almost any auto parts store) and they seem to work better:

When mine ripped I just put some black silicone adhesive on there to hold it together but still have some movement. It's all attached to the bumper via screws so it will stay on if those pieces are torn or missing. It just makes it look prettier when it's all together like that.

I didnt buy the Vette for the attention it gets. I bought it for the performance of the car and I have wanted a new one for many years.

Suuurrreeee you didn't........

I didnt. I have had Vettes (used ones) from the time I was 19 to 30. In that time I had a GTO and multiple Camaros. I got more attention from the bright red Z28 that I had.

Say I meet a girl and we are going out on a date and she doesnt know I have a Vette I wont drive it. I take my winter/DD Durango.

My Victory Hammer gets more attention than my Vette anyway.

I solved my scraping problems by backing in

it scrapes, it doesn't matter really. but it does need to be there.....all of it. as some have said it helps direct air into the radiator. nobody likes to hear it scrape but its designed this way and I was told from gm engineers at bowling green not to worry its supposed to hit. they want it that low....

:iagree:
Now this is a GREAT idea! Thank you for posting these screw rivets!

:cheers:

It does direct air into the radiator on the base and Z51 cars plus that is where the brake cooling ducts get their air supply from. Remove the air dam and there is nothing to create a high pressure area under the fascia thus forcing air into the ducts. GS, Z06 and ZR1 have the air inlet blocked off and cooling air comes in through the grille.

You can do all of the things noted above but why do anything. It is supposed to scrape and it is easily replaced when worn and the parts don't cost much. I don't see any reason to trim it since it trims itself. The sides on mine both wore out and I replaced them to keep my brake cooling. Mine scrapes when going over dips on the track at high speed. Turn 2 at the Glen has a little dip just before the turn in point and when I hit it at speeds above 90 mph I get a little Zitt noise.

Thanks for the info Bill........!!

This is what I did on my previous 2006 coupe.
