adjustable strut rods?

I'm thinking about getting adjustable strut rods. I have brand new bushings in my factory ones and they blew up about a year later. I also would like a bit better handeling so i was hoping to go with strut rods with heim joints with no bushings.

My first and most important question, can i put them in without pulling the lower control arm out? assuming i cut the old ones out? I hate cutting old parts but its a lot easier than removing the lower control arm, and if i tried to sell them nobody would probably want them like most of the crap i have sitting around here.

Secondly is it going to be a noticeable improvement in handling? Right now i have the biggest torsion bars, and nice big sway bars. The car seems to push a lot on low speed turns about 0-20 mph.

third what companies do you recommend for them? I'm looking for bang for my buck. If the 20 dollar cheaper ones are **** i would rather spend the other 20 bucks on good ones.
even if it wont help drastically it would almost be worth the money to me to not have to pull the lower control arm and deal with more crap bushings.
