Airdam size?

I just found out that my 91 RS has no airdam on it. I am in the process of making a custom one. What I want to know is how low can I hang it under the lower rad support without having some real scraping issues? So how low does the stock one hang under the lower rad support? Thanks

I was thinking about making one too. After I lower my car 2", it may have to be spring loaded

Re: Airdam size?

you know, this is off topic but it would be cool if these were kinda remote activated like when you turn your key off the air dams pull back into the car so they are out of site and make the car look better, but like when you turn the key on it comes down or when you reach a certen speed it would come down.

Re: Airdam size?

I've seen other folks talking about not liking the "looks" of the air dam, and I don't get it. Are you guys running Camaro bodies on jacked up GMC Jimmy 4x4 frames or something? Even before I dropped 1in on Eibach Prokit springs, the ONLY way you could see mine was to lay on your belly! Now, I doubt you'd see it even on your belly.

Why not save your fabbing skills for something more noticeable, and just get one off ebay, Hawks, Thirdgen Ranch, etc. - they are cheap. Even at stock ride height, they always scrape something (like driveway entrances).

Re: Airdam size?

they are about 4" long stock.

its probably best to use a stock one, they are flexible and will bend when you bottom out on them as opposed to aluminum or whatever else you plan to use that will just break or bend/crumple

Re: Airdam size?

Unbind your panties Evil ... Not bossing anyone - not ticked off - just curious that's all. Just my observation that it's not seen by anyone except the owner who knows it's there. So many folks don't even know whether they have one or not - many threads in the cooling forum about overheating and those folks don't even know what or where the air dam is until it's called to their attention.

Re: Airdam size?

You pretty much told him not to make his own airdam, if he wants to make his own, let him, and as for most people not noticing them, you right alot of people dont know what they are or where they are but if you look at your entire car you will eventually notice it, thats why i suggested my little idea.

It will be made out of a urethane material. Extremely tough yet flexible when needed. Urethane can take a ton of abuse.

Re: Airdam size?

well 'm prettymuch new to camaros and this website, but i had 1 guy tell me that he took his airdam of his '92 camaro saying that it was the cause of overheating on many gm cars around these years, i don't know what the airdam does exactly besides what the name implies; "air" "dam"= air blockage?

If you look at the front of a Firebird, you will notice that there are no holes in the bumper for air to hit the radiator.
The air dam deflects air upwards so that air goes through the radiator.



without the air deflector in place, all the air goes under the car and the engine starts to overheat while driving at highway speeds.

Re: Airdam size?

The air dam changes the direction of some of the air flowing under your car, by doing so it moves more air through your radiator. If you are having overheating problems it would be the first thing I would do. Here is a post where 89ROC-Z made one out of sheet metal. I think if you were to make one like that but out of some thick plastic it would work great and still be able to bend/crumple if hit.

Re: Airdam size?

It's my understanding that the air dam doesn't force any air into the radiator at all - but rather it creates a low pressure area behind the radiator (a vacuum) thus sucking cool air through the radiator.

Regardless, it is NOT any source of overheating - how could a piece of plastic not directly impeding any air flow to the radiator cause overheating? Someone's yanking your chain.

In town at low speeds, the fans take care of cooling. At highway speeds, even if the fans turned, they're useless at those speeds, and the air dam is a must or overheating at highway speeds is inevitable.
