On previous cars I tried coroplast skits and I could never get them to look good. In retrospect, they probably shouldn't have been exactly the same of the well, but perhaps just square, or only rounded on the front side.

It seems like if you had a curved, color-matched piece to connect the black body moldings on the rocker and under the back bumper; then a slot cut in the top could accept a piece made from your template. That would strengthen the lower edge, too.

Yeah. I agree. My first wheel well blanks fit the well itself. My current third gen extends behind the well. And I now think it is maybe too small. On this design I would definitely recommend a longer trailing edge to smooth the transition from the skirt to the rear bumper cover. Also, use the rolled plastic I used. Keeps its color and looks much better than coroplast.

I see what you are saying. How do yall attach such things at the top of the wheel well?

Traditionally, Dzus fasteners. I bought a scrap of plastic just to get a sample of this fastener:



It's spring loaded, quarter-turn to lock finger (on the back side) that would grip the edge of the wheelwell's lip. Dzus fasteners require a second part riveted or welded to the lip.

If you like running with scrap parts exclusively, or as close to exclusively as possible (as I do), then you might consider how I mounted mine: http://ecomodder.com/forum/showthrea...tml#post464528

I should warn that I expected this method to scratch the paint around the wheel well, but this was my third attachment method. All the others worked too, but I thought this was optimal in terms of durability, wheel clearance, and coverage--I I took the plunge and thought of it as a permanent mod. It has scratched the paint under the cover, not really badly, but yes... scratches in some places.

Hey guys!

Haven't posted in a while, but i got some progress! I made a heat formed pvc frame across the wheel well to secure a newly designed wheel skirt, shwn below. I couldn't find enough Cloroplast so for now it's fiberglassed cardboard.

Is the bottom edge rigid or flexible?

I think it would look good to have a ~2" black bar along the bottom with body color above, convert the crease in the lower front into a little air scoop and bring the top of the 'tail' up to the bumper cutline.

IMO it doesn't look half bad.
