Rear Diffuser How-to

Final segment of the custom ground effects kit – the rear diffuser fins. This works with the existing OEM part, and mine has the dual exhaust, but it really doesn’t matter. First thing I did was figure out a plan, and create a template out of cardboard. It took several tries to match the curve of the car. Any spaces and there is less for the adhesive to stick, plus it wouldn’t look right – it took me about 4 revisions before I was happy with it.

I painted these black, as well. They were used on the bottom to secure them in. On the top, holes were pre-drilled and then screwed into the plastic diffuser.[/url]
