I drive several miles at a time w/4.11`s but I run the hoosier qtp 29" tires so you`ll have a bit less circumference so maybe high 3`s will give the best of both worlds. By the way, it`s NEVER too radical to drive on the street........my small 470 has an 8" 5000 vert, 4.11`s, dominator and a solid roller w/.680-660 lift and 275-280 duration @.050 and idles like a kitten and cruises effortlessly.
