I have a set of 3.23 diff gears, and i was wondering about getting them put into my lsd diff, as mines currently 2.77. these gears came out of an XE, so would that make it easier to fit? i got quoted around 150 or so to get them done, also would it be better to go 3.5s? personally i reckon 3.5s are awesome, but i find they rev just a bit too hard at 100? would there be a noticeable increase from 2.77 to 3.23s?
