I am switching to the 3:27 gear. My 3:55 with almost identical combo puts me at around 5200-5500 rpm at the 1/4 in 4th. I think the 3:55 with the 2 step will alow me to run out 1st gear a little more which will help increase my 60' from a 1.85 to hopefully some 1.60's!
I think the 3:27 is definately better on the street for sure, the 3:55's make you have to shift to much. Oh im also running a 255/50/R16 M/T 26" tire
