Hey all, My speedometer is off... it shows around 5 mph+ SLOW. This occured after I went from 3.73s back down to 3.27s. I have a 315/35/17 rear tire <-- these must be the cause of it? What can I do to fix this, a different speedo gear?
Based on the table below I went with the purple 21 speedo gear from STEEDA for my 3.27 gears. I have a AODE by the way.
