You are right. I consider it a bug. ByTheWay: Sidestepping this bug you have to change the individual gears.
I usually encounter this, most of the cars has very limited or no gear adjustment at all. And when I see them I can’t distinguish if it should be in that way or is it something about under development. (They can gray them out btw if they are not supposed to be change)
thanks the problem is my max speed is circa301km in formula reiza if i adjust the gear ratio it still wont increase top speed as final drive wont change. example is like conrod straight in Bathurst or Hockenheim straight it just sits on max revs at 301kph if i can adjust final drive i should be hitting at least 330
Something that has allways disturbed me conserning the Final Drive setting in AMS2 is that when you change it it doesnt change the resultant values in the individual gears. Its a minor thing - but nevertheless most (all?) other racing games has this useable feature.
