Umm... what are these for?
 

I drive to work all the time seeing these little hatch back ricers. I have started to notice on a lot of them they have these odd Holes in the bumpers... and for the life of me I can't figure out why or what the hell they could be for?

So today on my way into work I took a picture of one with my phone (sorry for the quality).

Anyone care to explain it to me:?:

"Yes, there's a "Replacement for Displacement". Its called Volumetric Efficiency."
I was bored so I tried to find your answer on some civic forums. Needless to say, I am dumbfounded, and still have no answerr.

So the air doesn't get trapped in the bumper? Access to spots to tow them home?

I think they are places to put empty beer cans.

relieve air that gets trapped behind the bumper. Supposedly it serves a purpose on the actually fast imports but it seems to have been adopted by all the ricers that trap less than 100mph.

Since when I drilling holes in your car aerodynamic?

typically it isn't but if a body part traps enough air it will create drag. You won't catch me drilling holes in my bumper thats for sure lol

I kind of figured it was something to do with airflow. I do remember having a conversation once with Brandon about air getting trapped up under the bumper... but then again he has a 10.9 car and this is probably a legit problem for him. As for these ricers ... I just think if one of them does it .... they all do I guess.

hm.. always wondered what those were for

i work on honda and they are for some show but mostly the rear bumper hold alot of air in it

Speed holes flanders

yeah all of these are called rear diffuseres..i own a civic and im up on some of the dumb things ricers do. they believe air gets trapped behind their bumper so they drill a hole and put the diffusers on.

however, just now that entire honda scene is just now realizing its dumb and they are all stopping it now

So let me get this strait, they drill holes in a bumper..... on a car that doesnt go fast in the first place?

Thats where the VTECK gets its power from...

6 outlet exhaust!!!

Flux Capacitor

i call them speed holes...but they do serve a purpose if the car is actually fast

They're Dikfors (trademark registered) :rofl:

its to make it look like the bumper was removed...they aren't even holes just a sticker that looks like the bumper mount...seen it many times in my pepboys days

there are ones where you actually cut the bumper and put the metal insert in too

yea i've seen those, but they are 90% just stickers

for you maybe. every time I've seen it they've actually taken a drill to the bumper
