i read a while ago that car manufacturers intentionally have a 1-2% error when calculating speed. this way if you get pulled over for speeding you can't blame it on the car. so i guess if a cop pulls you over for going 56 in a 55 then he's probably lying.

And to run up higher mileage on the odometer, thus ending the warranty sooner.

my speedo is jacked.
GPS checked:
@ 45mph speedo reads 55
@ 60mph speedo reads 80
@ 75mph speedo reads 90
My mileage is completely thrown off as well.
These are the numbers ive had to memorize in order not to speed all the time. I also keep a radar det. on hand just for back up. Cant wait till I can get some new wheels/tires.
I did give my girlfriend quite a scare when the speedo read 135!! lol, not sure what the actual speed was though.

I am unaware of any gear change from the previous owner.. although that thought has come up before when I raced with other S2k's at an AutoX. I was reaching 4th gear on the long straight when the other S2000's where only about to redline in 3rd before they got off.

i put 245 re01r's on after my 245 050's same exact size, but gps now reads perfect, when before the speedo was like 3-4 mph high depending on your speed. the faster u went, the more inaccurate it was. now its only +2 @ 140 =D
it has to do with the diameter, not the width of the tire. some tires have slightly different diameters
btw there was a lawsuit against honda on the speedo reading ~5% high. i think they were forced to fix this for 06 and up
