I had 2.73 with open diff and changed to an Eaton posi unti with 3.73. The 1st couple of days I was kinda scared of it because there was that much difference in it. Now when I get on it and shift into 2nd it barks those 255/60's like a standard would. I can't wait to get back to the track and run it again...next weekend.

cool. i'm pretty sure i've got 2.73's now also. i can't decide wheter i want to go to 3.55's or 3.73's or if it would even matter that much betwen the two. i have to pay off the credit cards before i can even think about doing that though.
