thanks for answer but it is not an auto clutch matter, in GTR2 I have NAP MOD so I think almost for sure that FIA GT class in 2003 and 2004 used sequential gear with autocutoff.
Now here in RACE07 all GT cars (I don't speak about MODs , I don't have any, I have RACE07 complete) have sequential gear without autocutoff and WTCC with autocutoff, so, I have a G25 wheel and I can simulate properly all kind of gearboxes
so, does anyone know rules about gearbox in WTCC 2006-7-8-10 and GT classes?
