too flexy?....hmm...this thing would be my daily driver. on my k5 i went 8" lift springs all around

i was young and didnt know any better (16). im still young (17) but since then i have learned alot but still want a bunch of lift, but also wanna be able to actually USE it, although my 8" bds springs do flex pretty good for being so arched.
so what would u guys recommend then? its gonna be a dd. the 52s or 56s would prolly be 4" or 6". its gonna be a k30 so itll have 56s in the back already

it doesnt seem like the swap is too hard.
with just 52s does it move the axle forward, if so how much? would 56s do the same thing?
how do the 52s handle on the road? they arent too flexy for street driving right?
