I see where Im probbably not getting much effect from rear spoiler due to sedan with a trunk.
How do yall feel about about a crescent shaped extension attached to and protruding from top of the trunk back about 15"+/- 2".
I can trim it out of 20 gage steel so it will be strong enough to not flex down or up while providing flow separation over pressure stream from vaccumed cavity behind and below the trunk.

The crescent shape is to keep the unaware from walking into it and being hurt and hopefully to first mix blended side and upper side pressure stream from window height into vaccume cavity behind car slightly b4 the over car decompressing Air stream further entangles it.
Im just trying to reduce the parachute effect slightly because of side skirts and front spoiler.
I really wish I would have just went with full belly pans.
I hope someone can actually understand my description.

I have seen inverted spoilers on stock cars doing a similar effect where it sorta starts at mid tire height on trunk and sweeps up and back for 1-2 feet for blanket separation .

anyone ever gone here?????
