Torsion bar or spacer lift will add height to fit larger tires at rest. However, assuming you can still compress the suspension to the bump stops (i.e. have not cranked it up so high as to limit up travel) then yes, a larger tire may rub because it is bigger and the wheel well is the same size and position as stock. A mild body lift can help in those situations as can fender trimming:

Glad you finally chimed in. Thought you fell off the planet.

huh. kinda contradicting yourself there. first hand experience. without BJ spacers my 32s rub like crazy when my suspension was compressed say, backing out of a drive way while turning and stuff like that. now i have not rubbed once even at full lock and going into a driveway or something like that.

so that must mean that i was able to run a bigger tire without the rubbing issues.

the Tbars mount to the upper control arm, the lower control arm simply follows the path of the upper. so when the BJ spacer are first put in they spread the arms, since you still have the same tension on the upper arm all of the spread will be applied to the lower arm. hence better upward travel, but still the same downward travel. Now if you relax the torsion on the bars then the upper control arm will have more space between the bumpstop & the control arm (due to the weight of the truck pushing down) this improved distance between bumstop & control arm will give you more downword travel (at the expense of upward travel). So to get more travel than the extra that the spread of control arms with the BJ spacers gave you, them you would need lower bumpstops - but you may be killing your CV angles then.

Not really... since you have an increased stance during street driving you could get away with a tire that would rub at stock height, like your 32's. But if you were to drive somewhere other than the street or your driveway, like a trail or even FS roads, you would experiance rubbing in the same manner as before. You suspenion cycles the same as it did before, just 1.5" lower on the droop side, otheriwse its a stock cycle.... Its a smoke and mirrors game...

Oh.. your talking about the ratio of upward to downword travel, not increasing overall travel, since when you add lowpro bumpstops you loose tire clearance....
