You’ll want to establish a center line reference first. Then measure the distance between your pylons. Then figure out half of that. Then measure from your centerline out by that half figure.
In other words, if your pylons are 20″ apart, you would want to make a mark 10″ from center on each side. This will roughly indicate where your pylon’s center line should sit. Note that your pylon’s tabs may not be exactly parallel to the centerline of your vehicle.
You’ll end up with a bunch of marks like this.
Just make dots through the holes with a marker or pencil or something. I chose to drill a pilot hole, and then a hole slightly bigger than the bolt’s thread width.
Carbon fiber dust is nasty stuff. Use protection.
Carbon fiber hoods and trunks especially have lots of support structure inside them. If one of your drilled holes ends up coming through one of these support ribs, you’ll need to make a large enough hole in the support rib in order to get clearance to get a socket onto the nut that goes on the backside of the bolt.
Yes, that’s actually a bunch of crappy fiberglass on my carbon fiber trunk lid. If you recall this car’s history, it was actually abandoned at a stereo shop where it had been getting a system which included subs in the trunk lid. I did the best I could to chip it out and clean it up.
Anyway… once you clearance the holes on the underside, you can bolt the wing to the deck lid. You’ll want it tight, but it doesn’t have to be crazy tight. Remember that the wing is pushing down into the deck lid (downforce), not pulling up (lift), so they’re mostly there to keep things in place. That being said, too tight and you will crack your fiberglass/carbon fiber. You can be less careful on a metal lid.

“But there’s an end to this means, I assure you. And it’s not another innuendo. I don’t think. If you look back to the photo of Rob, he’s taking a photo. In fact, he’s taking dozens of photos. You see, when you take dozens of photos from different angles of the speckled car, you can then use some really fancy computering to stitch all of the photos together to build a really accurate 3D model of the vehicle.”

Rob is using a regular digital camera and then stitching 2D photos together using software to build the 3D model.
