Very nice and stealthy. Thanks for all the how-to photos. I will copy this on my car next spring. What was the best method of cutting the polycarbonate? Jig saw?

Why doesn't the wheel skirt go all the way to the bottom of the rear bumper and the bottom of the side skirt ahead of the wheel? Is the way they did it more aerodynamic? Is it just for looks?

Also, you can use a heat gun to mold plexiglass and lexan. I saw you used clamps which probably worked fine, but if you get it in the shape you want and heat it up, it will kind of conform permanently to that new shape.

Those look very nice BTW and has inspired me to do the full moon hubcaps and then rear skirts on my civic hatch.

I don't know but I will speculate that it's an aesthetic choice because the angle follows the character(?) lines of the bumper (upper white line) :



I think they could have gone down to the lower white line in the above picture, but the tire is starting to jut out more because the body of the car is tapering inward :



I made a similar aesthetic choice for mine :



That's not a pure side picture, but I think you can see that I am angling it upwards (ha ha, kicking it up a notch).

there comes a point where the lower you go, the more tire exposer your having to deal with. which translate into curving out from the body. the braking of the flat plane then will create turbulance at those points.
(All this of couse is 'imho')

Looking at the rocker panel,it seems like they've extended the panel downas low as they dare before it strikes the tire sidewall.If the rocker panels were more flush with the outer face of the tires,they could have continued them down as with their C-111 III of 1978.

The top half of the tire is spinning against airflow - this is what we don't want. The bottom half of the tire is spinning with airflow - so there's little to no gain. Hth
