i had 3:73 and put 4:30's in, if i could go back to the 3:73 i would for the long haul, on the street the 4:30 is just totally sick, but at 80 mph i am screaming and it sucks ass. luckily i dont drive on the highway much, but now if i want to, i really cant for long or i have to keep it around 70. having both gears i would say the 3:73 unless you only do city driving then i would say the 4:10.
^^^ speaking of my 3:73's danno!!
