I have a nice pile of cardboard now--including some big sections--and black duct tape for building and testing designs.

I need a little help re: mounting points for a diffuser/undertray. Has anyone done this on a 6th gen Civic that might share ideas for where and how to mount the undertray?

I have read brucepick's thread: http://ecomodder.com/forum/showthrea...tml#post225094. But his rear diffuser seems to be curved a bit, and I'd like it flat and adjustable in place, so I anticipate I need some way to suspend the aft edge below the bumper.

In this pic and in some of the other pics attached below, you can see parts of the chassis from which I might mount rails. Any advice?
