Just a quickie... What is the optimal rev value to change gears in HistorX? The pdf advises you use the cars power value. So for the Alfa Romeo GTA this is 115kw@7500. Therefore I have been changing up at 7500 rpm. However I just noticed in the garage under 'General' it says the rev limit is 9500 rpm. If I was to use 9500 it would mean changing the gearing in my set ups. Is that too high to change up? What do you lot advise? Thanks in advance.
