you diddnt find kits anywhere for v6 f body's. Currently there are no bolt on kits avaliable. If you want one, however, Force fed fabrications can make everything you need.
the only thing that i have found different between the gt and the f-bodys is the way they respond to tuning.
I had my camaro tuned by Gary and if you are familar with the guy hes great at the gtp's, Has it down to an art. Unfortunately when we bolted the gtp's sc to the car, his tuning skills were no match for it. I ended up going to a good friend of mine and we shifted through it and sorted it out.
