I've installed and tested out this kit minus the sway bar. You can see the write-up I did for it here:

For the most part, it's a great kit and the control arms are about as good as they get. What I wasn't thrilled about were the coils as they are progressive. They provide plenty of droop but don't stuff as well as I would prefer. Also, I wasn't too happy with the ride they offered but, ride comfort is 100% subjective. As far as the Anti-Rock goes, I would pass on this as the factory swaybar will offer much better stability and won't squeak like a banshee. Plus you save a lot of money by not getting it. Last but not least, if you're willing to weld, I would pass on their relocation brackets and dropped pitman arm and opt for something like an EVO drag link flip/track bar relocation bracket. It's a much better solution to steering geometry correction.
