Hi I was wondering if someone could reccomend the best diff ratio for XW/XY model with a 351 and c4 auto in it.
I want something that fries em up when you want to but still has a reasonable top speed and fuel economy.
My brother just fitted 3.7:1 to his VK commodore, it lights em up but his at max speed around 170/180 and to top it off it is reving pretty high just at normal speed of like 120km/h which means quite thirsty.
Anyway hope you can help
thanks guys
