Yea I like 4ws but bolt ins are usualy high price no matter where you go, 4:10's will not due the trick I have a set of new 35's and will probably go bigger if i can, so looking at 4:56 - 4:88, I know a couple guys running 35's with 4:88 and they love it (they have Rubys).
An 8.8 with 4:88 and I'd like to have a 44 front but if 4:88 will go into a d30 I'll run it.
