i have broken a left side outer, and a right side outer CV on my vit. i am running the 26 spline shafts. i can also break the CVs at will if i want to, its not hard.
although, i am sitting about 3" over stock ride heigh on level ground, and i have about 4" of droop on the fronts. i have no front diff lowering (yet!), and so this is where the CVs are weakest, at full droop, and any slight turning or steering will see them spit metal balls and cages.
each time, the cage has exploded and the inner flower also broke into as many pieces as there are balls! so yeah, with a lowered front diff (2") and less droop or extension of the shaft will see them last quite a bit longer. in stock form, no lift, they arent really that weak IMO.
as for sway bar(s), well, there's only one, and i...ummm...well..it fell off one day, and i sorta lost it. i think it was the 2nd or 3rd day i bought my vit. a vit is 4" wider than a WT sammy, and with some 3"back spaced wheels, a hell of a lot more wider, so on road i'm not an F1 or NASCAR driver, i just enjoy the body roll, and the comfort of coils (compared to a sammy)
