Thanks for starting this thread. I've been considering going to 4:56's when I move up to 35's, based solely on rpm/gearing charts :doh: . But after reading what Matt has to say about his highway performance I'm glad I didn't. I guess it'll be at least 4:88's now.
that's cool, but you should do ones for different overdrives also, the 23 spline AW4s (92+?) have a .75 OD, the 5 speeds I think all have .79. of course I have a spread sheet where you enter the speed,tire size, diff gears, and tranny gear and it spits out the RPMs
