Uhm, those aren't GT class cars.
GT class cars are, corvette, saleen, ferrari, porsche, panoz, aston martin etc.
Cars that are normally in a production class but modified heavily, what we already have in LFS(XRR, FZR, FXR), considering their "production little brothers" (XRT/XRG, FZ5, FXO).
Lolas, Audis, Peugeots, etc. are prototype race cars. But yeah, would love those.
