Finally, a picture of the airdam/chin spoiler. This is the prototype. I will cut a new one with the centre cut higher and with the coroplast tubes running horizontal. I'm also going to check out the lawn edging to see how that might work. So far the butt-o-meter reports better coasting but that's not verified on my known hills.
It's attached with angle brackets sheetmetal screwed into the lower bumper edge. Easy installation. Coroplast has straight top edge.
