my speedometer is off a little. It's about 4-5 miles per hour fast. Meaning when I'm going 75 it reads 79-80. I've tested it with two of my other vehicles side-by-side while driving on the freeway. I have the stock potenza tires on 225x45x17 on the stock BBS wheels. Anyone else's speedometer off like this? Is there any way to have it re-calibrated? maybe the dealer?

I have noticed the same thing. about 4 to 5 miles per hour faster, even when i get clocked by those automatic speed things that cops put out to see that you are speeding. i'm 4 to 5 faster on the speedo. i wish we could fix this and if anyone has a suggestion please post it.
