1993 Chevy Lumina sedan build thread

Interesting. I opted not to make access panels and to just keep a knife in the car to cut the wheel covers off in an emergency. Keep us updated on how the flaps fare- a few people here have had trouble keeping things in place at highway speeds. They look cool though, like those Mooncraft covers for Prii.

I guess I should be more direct. You might consider adding a few more patches of Velcro on there.

Today I got the wheel covers on my car and they look pretty spectacular. The inner circles stick out a bit because of the method I used for velcroing them to the main disk but at highway speed going up to 65 mph today for a few seconds, I managed to have nothing happen to them (I had a relatively short trip to work). Below are pictures of my results.

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.

I would use some sort of backing as the zip ties will eventually work it's way through the Coroplast from the buffeting/flexing. A wire hangar would work quite well to distribute the force and keep the zip tie from cutting through.

I would do an overlap type of joint instead of a butt joint.

Today I completed making my rear wheel skirts and putting them on my car using heavy duty velcro ULTRA-MATE (R), 4 ft per skirt. They feel pretty solid stuck on so I'm not very worried about them blowing away with only velcro to have them attached to the vehicle. Below are pictures of the results. I still need to paint them my body color of course.

P.S. My dad saw the unpainted finished product and couldnt stop laughing. I must be in the right direction.

Today I finally redid my grill blocks and used velcro on the edges to hold them down to the car. Below are pictures of the final product.

My rear wheel skirts are completed, painted, and ready to go... except, my dad has made me fear putting them on because he feels they may rip off at high speeds and cause an accident which is possible so I need some help/suggestions on what I can do to ensure my rear wheel skirts dont come off.

I was going to use high power rare earth magnets to help hold my rear wheel skirts in place when I make them.

I share your dad's concern regarding velcro holding the skirts. Velcro will deteriorate over time, being exposed to the elements. You can't beat stainless steel 8-32 (or 10-32) screws and lock nuts.
You could look through the Project Library for inspiration on various attachment strategies.

I'm glad you found a way to get your paint to stick to the coroplast. I cheaped out and used Krylon Fusion spray paint on my grille block.

Zip ties are a great fastener...

TC, all you need to do is buff it with 600 grit sandpaper and it's ready to paint.

Lookin' good here. I just duct taped them to the fenders using red duct tape. Absolutely no problems. You can probably remove tape goo with rubbing alcohol, if you're worried about it long-term.
