I'm in the process of making rear wheel skirts for my car. The coroplast I have is not large enough so I'm using two pieces joined together with black cable ties. Its looking good so far but right now, my primary concern is the necessity of using a support bar to keep the skirts from touching the wheels. I'm using 4 feet of 1inch velcro to attach the wheel skirts and it looks like there will be about 1 to 2 inches of clearance between the wheels and the skirts. Given the not entirely stiff cable tied skirts, there will be possible bending occuring at high speeds. Bernoulli's principle means that the high speed air going across the skirts should cause a low pressure, making the skirts bow out which means I wouldn't need a support beam. Thoughts, opinions? I will upload pictures later today.
