ok, so I have not used GPS yet to check for sure but with my wife following me I showed 55 on the speedo and she showed around 70. I have only had the car for about a month but it baffles me why the speedo would be off in this direction. Follow me on this, if you put a larger tire and wheel diameter then get the right gear to adjust then slap the factories back on (smaller of course) then the speedo runs fast. The same if you dropped from factory 3.42 to 3.73, speedo reads faster. I'm pretty sure I have a factory rear end and the G80 works. But I'm baffled as to why the speedo would read so slow unless they put smaller diameter tires then back to factory 15s which makes no sense. Maybe I have it all wrong and it's a defect in speedo or something.
