opinion on sway bars

[fdbdw]

I think Im pretty much sold on adding a front sway bar, just not sure were im going to buy it, probably LMC ( comes with brakets from them). But not sure if its worth it to add a rear sway bar, I just put on a new tracking bar ( the one that hooks to the frame and diff). Do you guys think adding a rear sway bar along with the rear tracking bar would be benificial or over kill. Any advice on Brand or company to buy it from I need the brakets also.
