@daan is just doing his job mate and if there is someone with a setup they will help you out, but unfortunately GT Sport tuning forum is very quite.Very good!
Due to the multiple updates to the physics of the cars, I think if someone could contribute something it would be of great help. I am also looking for the adjustment of this model and those with more than 1 year. As a moderator I think you should be aware of updates or at least how to respond to new users. I will look for luck in another forum and I wish you luck also with your forum, since with the treatment with which you address your users, I do not see any horizon.
