I'm quite pleased with the look of the Autometer speedo. It goes up to 260 and has large numbers at 40KM increments and smaller numbers at 20KM increments. This means there is an obvious mark at the common speed limits of 60K 80K and 100K.
I must admit the 300KMH speedo has the bragging rights though. As long as you have the go nedded to get you up there.
Dick Smith's amazing 198MPH equates to 318KMH That's Fast
Cheers
