[Austin]

i would love to know how fast i am going without the use of my satnav!!

i have 165-50-15's up front and i know my speedo is way out, so i rely on my satnav, what clocks are people using for an accurate speedo reading? and also, not being thick or anything, how do the after market items give you an accurate reading when the standard one cant after changing rolling radius?

cheers

satnav I'm afraid as there is know way my bus will do the H on the mph on the speedo :lol: :lol:

you can get the re-calibrated but its more fun to watch peoples faces when your doing 90 +
