My N2itive camber bushings have an 8-year warranty? The rear right unit rattles like crazy from worn bushings, about 16 months and 20,000 miles of use, and 6 alignments. When I bring it up I just hear “who installed them” (me), and the case is closed. I torqued at ride height, which can be a process, and it seems to have made no difference. Maybe an alignment tech loosened and retightened the back corner when it was up or something. Based on cost, difficulty of adjustment, and my personal experience, I would look to a different vendor. Beautiful parts to look at in the box; the bushings are robust and one end flexes dynamically, but just not so great for everyday use imo. Wheel off alignments ($375) are required to get it dialed, or you can make micro adjustments and bring it back in and see how close you are, something I sort of learned was the better method to savings.
“Saving” my tires with toe and camber arms, all the alignments, we are talking $2,200+. A set of my favorite tires last 25k miles for $1050. The arms will pay for themselves in 2-3 years, but with 220k miles, I’m not so sure the car was worth the parts.
