The difference between 5.13 and 5.38 is only about 150 rpm, if I recall correctly.
So unless you really need the 4:1 tcase, is a Rubi worth the extra 6-7 grand for those 150 rpms? Not to me.
I may be talking out my ass tho, because I’m putting 5.89s into my Rubi 44. If I hadn’t picked it up for the steal I did, I would’ve built a HP30 no doubt.
Yeah, I definitely will admit I don't really have any idea what the rubi premium adds to the LJ yet. Haven't gotten that far yet. 4.10s and f/r lockers will be AMAZING (compared to my current setup) if not ideal for my end goals - and an Atlas 2 is not cheap. But really, that will kinda depend on what my TJ sells for and how much I have at the time.
