Bitty did right to build a TT version of the 599. Maybe they will follow up with the other releases that are coming, eg. Aston, Toyota et.
I asked Bitty about a Porsche 963.. they said they had no plans to do a Porsche..
The track in my area that run LMH are quite big. So the 25.5. motor doesn’t inspire me to dedicate a more advanced chassis to this class.
