Speedo Calibration

Unread post by Brewster »

Just had an inquiry about speedo calibration, Friend of mine has a 95 Mustang GT and re geared as well as a different tire size and the speedo is now out quite a bit. Is there a way to fix the speedo ?

Yea that's what I thought may have to happen, wasn't sure if there was some other magic behind it on those as I haven't wrenched on them much. Appreciate the info !
