this might sound like a crazy question but i am wondering what revs your zd30 powered nav is doing at 100 kph?mine sits on 2650 rpm and thought it might be interesting to see if there is much difference between vehicles.
Going to check mine after work, Wouldn't tyre size make a difference? How many people have changed their speedo gearing? If you have non standard tyres shouldnt you say if it's speedo or GPS speed, with my 265/70/16s the speedo under reads by 5-6kph @100
Id like to see what the D22 STR's with 3.9 diffs do.
