The STCC is a “Touring Car” Custom race event on Gran Turismo 7, utilising the Sophy AI option and across any and all applicable tracks that you want to try competitive racing at! I have spent time trying to manually balance the tuning of the cars, as well as adding new additions when they are included/updated in the base game. I have tried to work to a 700pp baseline, with some manual overriding to boost certain underperforming cars on-track., and all settings sheets are a “general” tune that may work better/worse depending on the track chosen.
