Not sure if this is a good place for the post but meh lets see hehe.
I had one of those huh what if thoughts pop in the old noodle. Corvettes have a ton of plastic under body covers to help with drag i believe is the term. Us camaro firebird guys have no such thing hehe.
Anyone have any thoughts on the what if this was done to a camaro/firebird? Im not sure if the added weight could justify doing it for just 1/4 mile racing. Im sure road racing could see some benefits... Has anyone ever tried to make the under side of their car like a corvette?

heres what i did/do
tape on the nose

this allows any air to escape from the rear bumper area. the liscense plate is on a hinge

small diffuser i made, so that the rear bumper dont act like a parachute.

also added these 4 holes to the left and right of the plate for air as well

I would think the holes in the rear bumper would cause a vacuum and cause more air to pulled up into that area.
I run a rear undertray like you but without the holes.

i thought up a really good idea some time ago.
A flat underbody helps air travel smoothly and keeps it moving fast without creating to much lift or drag being caught on **** like our gas tanks. (correct me if im wrong im not a aerodynamic engineer)
So I thought what if you bought a very large rectangular piece of sheet metal (very thin piece) and found stock mounting points and holes and make a template to cover up any gaps. However you would have to have some gaps to let hot air and other things escape. I think the biggest area of concern is the rear section.

refer back to my post w/ the pics, under my name i said i dont have back to back testing.
also i would think these little things are helping as i am gaining anywhere between 26-30mph on the back half and have trapped a best of 127.43 might work or might not jmo
