I'll put it another way. On a track doing speeds between 60-200km/h. The car is light enough and the engine makes enough torque that slightly taller/longer ratios wouldn't slow it down. Taller ratios mean you spend longer in each gear, power is more usable. Less shifting.

I'm not touching the final ratio, it's a torsen centre and seems to do what it's designed for. I'm thinking about a tougher, much more refined gearbox that is available with the std Commodore ratios as well as the taller ratios in the screenshot above. It may also provide a better location for the shifter - waiting to hear back from Mal Wood on that one.
