It is also for when you race on the salt plains. It prevents 1 drag and 2 sand from getting back there and slowing you down and destroying yo shit from the salt.
someone on here explained it in a good way, so ill do it the same way...
your back bumper acts as a parachute, air gets trapped in there as the car moves forwards, parasitic drag= slow car down, holes allow air flow thro the bumper instead of holding it there creating drag. but like "thermal" said street cars have no real use for them.......
I wonder who that was
(thats the same way I describe it.

Any fact about that? That'd make for a good history read. Post up a link?
All the super fast street racers have them, which is why I don't have them.
It would probably be better to cover the bottom of your car with a sheet of aluminum to prevent drag all along the underside.
Yeah, but then you are going to have people comment about that being ricer and you will mess with the aerodynamics design of your car and create lift at higher speeds.

damn jarrod you think im on your nuts or something? lol, it deff wont you who described it, where i read it. i read it on here by some guy with a all out race car hacthback for-sale and he had those holes.....maybe 2 months ago...
ill just remove my rear bumper at the track if i ever feel like its acting like a parachute.
Yes sir. You should try it. It's like 9 screws to remove the rear bumper. Would you try it to see if it help'd? I mean, at your E.T and trap, it should.

won't create lift. A fully smooth underside should create downforce..
