well 3.73 gears are usually a pretty good ratio for 1/4 mile runs. 3.42's u have to shift into 4th usually right at the 1/4 mark...

Your MPH went down quite a bit.. your 60 wouldnt affect your MPH.

Weather can kill though your times... or because its near gearing your not shifting at the best points anymore cuz ur not use to it?
