I passed a radar speed check last night and noticed that my speedometer read 60mph while the radar clocked me at 56mph. Has anyone else noticed if their speedo is off?

I passed by a couple of those, and never noticed a difference.

It depends on how fast you are going. The faster you go the more inacurate it will be. The stock JDM tire size is 185/65R15 so unless toyota/scion chnaged the speed to go with the stock 185/60R15 tires we have that would cause a inacurate # right there.

Virtually all factory speedometers read a bit high. If they read low, drivers would blame the manufacturers for their speeding tickets!
