GoKart and Me!!!
Like the title states, I need to get my speedometer recalibrated because of my aftermarket wheels. I found out, while using my GPS, that my speedometer is 3-4 miles ahead of my actual speed. For example; speedometer would read 70mph, but GPS is reading 67mph. Is there an easy way to do this or am I better off taking it in to the dealrship and have them do it or just leave it and do the "Kentucky windage" thing? Thanks in advance.
