is it possible to extent the available seat height adjustment. some cars like the new GT Corvette seem to be limited. is there a moddable .ini file where I can adjust the available range.
No, for cars like the GT3 pak that are encrypted. Which means we cannot access the files inside. But other cars are open and can be at least examined to see what changes can be made. Pretty much you have to stick with modded cars or ones that ISI/S397 left unprotected. I don't know which cars are unprotected though, perhaps somebody else can add more.
The only thing that I can figure is untoggling the camera (U) and moving the camera manually with keyboard inputs previuosly assigned. I know it is not very robust since a slight movement of the mouse can ruin a race.
