I'm amazed at the off the line ability that my VX has WITH 33's (more that it's not that much different from stock), so if it'll improve with 4.77s, I'll start looking.
That's a 1.6" increase on the radius (about 10% reduction in accel). I think? Seems to me that would be very noticeable.
3" suspension lift, shocks: Rancho 9000, tires 33"x11.5", wheels 16"x8", offset= 0, no front sway bar
