Cadillac CTS-V - Custom bumper speed holes?

I know I asked this before but could not find it.
What are they?

Funny

I missed the humor I guess.

Do you have any pictures of the "speed holes"?
I did a google search and could only find info about some Honda bumper holes but nothing on a Cadillac.
Are they on both the front and rear bumpers?
How many holes are we talking here?
What sizes are commonly used?
Do they add speed to the vehicle or do you need speed while making the holes?

Some pics would be great. :corn:

No pictures as this is a very delicate and time consuming process, each hole adds roughly twelve to 13 HP at the rear wheels. Another good option to getting this effect is too attach a type "R" badge to your car. Break out the rivet drill.

Seems useless for a car with a plastic bumper. A splitter and diffuser would be ideal for track days.

Before this thread gets too complicated, they are just the holes left after pulling the front tag bracket off.

Oh well hell i have those already :)

Ummm, WTF? Holes that make you go faster? Sign me up! hahahaha

My understanding is that a rear diffuser is only functional if the underside of the car is flat paneled to where the air flows smooth

The last question?! Lmao do u need speed while making these holes?!?
I can answer that one!
1. Do some speed.(not familiar with this so do some research.)
2. Get a friend
3. Get a drill with a 3" hole saw bit.(tried all different sizes 3" is best)
4. While friend is driving at speed(i find 88 to be the optimal speed for this), you lay on the hood performing a reach around(that's the technical term) and drill 9 3" holes spaced approx. 6" apart in the front bumper.
When finished outline each hole with chrome pinstriping for more efficient air flow.

DONE!!

Man, you had me rolling. You should have let this thing go a few pages before the truth came out.

Just wanted to make sure the first threads were quoted JIC the OP decided to "edit" anything. LOL

This is making my day.

I just stay stocked on Elbow grease. Nothing else really cuts it for me.

OP, the concept behind it is aerodynamics. They think that because there is drag from some air flowing under the car, that it goes into the bumper and basically becomes a pocket of air which drags the car and slows it up...

Truth of the matter is unless you are trapping 125+ IMO, its nothing where it'll affect you and if you really wanted to do it right, cutting holes in a bumper isn't really the correct way to go about it. Its just the quicker, cheaper, and uglier way. A belly pan would be a better alternative. I'd go with what was mentioned earlier... a splitter and diffuser would be the route i'd take.

Can someone post a pic of the "perfectly clear" tail lights. I'm at work and they don't seem to be loading.
