I am interested in how that Addco works for you. I took the plunge and bought the Hellwig expensive ones. Both front and rear. It is a lot of cash but Rather spend once than do it then do it again.....
I'm usually the same way. The hellwig is a beast and the ability to remove it is a nice bonus for rock crawling.
After thinking about it, though, I realized if I could pull it off one of two things would happen: I'd leave it on and never take it off or I wouldn't like it, take it off forever. So the Addco made sense for me.
So far so good, but I won't really have an opinion until I get back from my commute tomorrow. I specifically had a problem on corners feeling floaty at 45-50mph on windy roads. That's why I bought it.
It is quite a bit rigid against the bouncy suspension, though. It's noticeable but not annoying with the front sway, I absolutely wouldn't put a rear on. The ride would be way too rigid on bumps.
