GTPlanet is not affiliated with Polyphony Digital, and suggested content posted here is not guaranteed to be noticed by PD, let alone earmarked for inclusion in the video games.
Furthermore, all content suggestions made here for the Gran Turismo franchise should go into
the “Suggestions” sub-forum of the Gran Turismo section, and if you want to make a suggestion there, make sure you do a search with the relevant parameters beforehand to check that the same suggestion hasn’t already been made, and make sure you adhere to the guidelines that are at the top of the first page when posting. Alternatively, there’s also
this thread, which is littered with myriads of things that people want to see added into GT, so it’s more disorderly.
A quick search with the first method has shown to me that many of your suggestions are already suggested, but there’re some cars that didn’t have your exact specification suggested, like the Corvette C6 Z06, so I think you can create a thread for that in the Suggestions sub-forum, provided that you follow the guidelines.
