I have a relatively huge "wing" I built for the rear end this spring, that is the one I referenced as a kamm shell that I need to do more work to because the leading edge transitions are not smooth enough.

I did an air dam on my last two projects, but I am trying on this one to do a belly pan system and smooth the airflow through the underside versus directing the air around the sides. This approach is used on some production cars (e.g. tesla) however it puts me in a non ideal interim situation seeing as how I don't have the belly pans done yet.

This vehicle is built around compromise between on-road use and off-road use, so I am not looking to reduce ground clearance for off-road reasons. My front end is technically stock height, but mine has the "99 tall" springs (from factory) so it is the tallest "stock" 3rd gen 4runner. (Other year third gens often order the 99 tall springs as a "lift".)
