I need to build a similar air dam for my car. I was wondering if you could tell me what thickness aluminum yours is made of, and would you have used the same thickness again, or a thicker or thinner piece of aluminum? Yours looks pretty nice.
Also, has anyone made an air dam out of steel? What thickness? I have a spot welder, but no way to weld aluminum so I was thinking steel could be easier for me to fabricate.
I was also thinking of making the bottom 1-2" of the dam out of some 1/4" firm rubber. Good or bad idea? What ground clearance is commonly used?
Thank you,
Jeff
