Speedo variance?
My speedo is PLUS 3mph at 60. I'm wondering if any of you have checked to see what your variance is or if this is specific to my car since I run 19" wheels?

AFAIK all of them display speeds faster than actual....this in part due to a fine the manufacturer could receive for having the speedo report lower than actual...3mph@60 sounds about right.
