Wen driving and go past a speed sign, my speedo tells me im always doin 10 mph faster then what i rele em, and wen iset the odomemeter to the speed, it says same thing, speedo was 10 mph faster..Is it possible i have gears in my car?... i hearalittle whine to commin from the rear.

Also though i have a 2000 gt, but ibaught the car with6 cyl rims on it tho.. i think there alittle smaller, but the tires are still pretty beefy, could that be the reason y the speedos off?

Iam at the gas station every 3 days tofillin it up, so i think i might have gears, what u guys think?

Easy way to tell is to jack the car up and rotate the drive shaft. Count how many time you have to turn it to get the tires to spin around one time.
Also, the tire diameter could throw off your spedometer, but not by 10 mph.

sounds like you got 3.73s in there as opposed to 3.27s. i had 3.73s installed before the speedo recal. it read 10 mph faster than it really was
