Mounting a wing
How do these mount ? Just straight bolt to the deck lid? Any structural supports that need to go under the deck lid?

This is fine for TT, very common in NASA for instance. However, no race car should run a wing that isn't structural to the frame. If you hit something (a competitor, barricade etc), inertia will cause the wing to either rip your decklid into pieces or likely rip the entire decklid off of the car.

Mine works just fine for HPDEs, if I was racing the car, I would go to a frame mount for better down force and a more secure mounting. JD

I've seen a few cars with these mounted to the deck lid with no re-enforcement to speak of. 3 small bolts on each side. Not even a solid mounting plate under the trunk lid. Surprisingly I saw no cracks in the fiberglass around the mounts.
The one person I talked to told me on a C5 it was a royal pain coming up with mounts that didn't cause the splitter to rip up easily. Also, don't have an off with the splitter attached...
I bought a used COT wing with road racing end plates. Very nice piece of hardware. I've found someone who is willing to make me frame mounted plates and adjustable upper arms so I can play with the height. Once we get the details worked out and get it to work I'll pass the info along. We'll work on the splitter next to also have it braced off the bumper. Some of them just use small bolts with nylock nuts and a washer behind the plastic bumper. That won't last long. Pay attention to the mounting kit.

Should be able to support you body weight.
Think of the loads generated.
I've seen them mounted to the deck lid, but there there's a structure underneath that goes down to the frame.
Same for splitters, if you can't stand on it, it's not mounted properly.

Yes the wing should be connected directly to the frame in a ideal world. All of our race cars are done that way, and that is how I sell our mounts for the GT2 wing.
You do see a lot of 'wings' out there that are deck lid mounted, but just like everything else in this world one wing is not the same as another. It may not have that much angle to it, or it may not produce enough downforce to do much more than compress the bumpers and weather stripping around the deck lid so you might not see cracks in the glass so to speak.
You have to think if you are going to do some aero work to the car and want to make 200-300 lbs of downforce on it, it should be able to support at least 1-2 people on it.
Take for example this un-orthodox picture from the guys at Blu808 that use our wing and mounts on their FormulaD Corvette.
Now on some of our older TransAm series cars the wing was mounted to the entire rear body work of the car, but there was frame supports that came up to meet that body work and they were attached using the deck lid just as a sandwich material so to speak.
