Nice pics, I agree those hooks look better. It would be interesting to know which car they actually modeled initially. The kit has two wings and a few versions, so I have no idea, but I'm guessing whatever it was had a hook like the one they used.
I Googled for hooks and found this one, which I'm sure you must have seen - the Tamiya hook could be easily converted into something like this.
The GT3 Cup's hook is vaguely similar to the Tamiya one (ok, very vaguely!). Anyway, I don't mind the hook so much, but the vacant license plate well does look pretty bad. You should definitely go with a nicer version - your model deserves it. Mine doesn't, lol,
