Has anyone done this on a Gen 2 car?
I can’t figure out where it’d make most sense to install some support to keep the trunk from bending/flexing with a wang. Would it make sense to replace the rubber supports on both side of the latch with hard bolts, and removing the plastic piece on the edge of the trunk so the bolts have a hard point to rest on? |

You can mitigate that with a backing plate on the inside to distribute load across a wider area, if you have room on the inside of the lid. It will probably still flex, but should help it from tearing. I am going to have to do that with the little APR universal mounts I bought.

Yeah, a lot of reinforcement is needed for deck-lid mounted wings. It's pretty easy to make a few hundred pounds of downforce at high speeds, and even more at "peak" (ie: strong head wind + high speed).
Most mounts have fair small footprints- maybe 8-10 square inches at most. You're talking hundreds of PSI there.

Rubber mounts are fine, IMO. If anything, they can flex a bit and that's a good thing. Maybe just make them bigger or more of them. The Viper ACR, which has a MASSIVE "double decker" wing that is deck mounted, runs rubber mounts. They just have a bigger landing pad than the non-acr versions. I think they also basically bond a second layer of carbon to the deck lid. A little different, as it's a pure carbon body panel, but same concept.

I actually really like the wing mounts on my GTC200 and have been thinking about reusing them with my new wing. They have a very large footprint.

Yeah, those are monsters. Not very aesthetically pleasing, but great for load distribution.

At the track yesterday I noticed that the rear mounts were pushing down away from the bolts. These were tightened down to the point of bending the the trunk a bit with a backing washer. On the top I am using backing washers, but I'm highly considering building some plates similar to the ARP ones above.
