The Calmini kits look good and I suspect they are of high quality. I've used Calmini parts on a Samurai I had a few years back and those parts were of extremely high quality. The Sammie is a whole different animal than the Trackers when it comes to lifting. I looked into a Calmini lift for my 2000 Tracker and its a 2.5" which is a little more than I wanted to go since I use mine on the hi-way also. I live in the desert so its not uncommon to have a 30 or 40 knot cross wind at times which makes a lifted vehicle an experience to drive!
