Jeff,
I know of a couple people running the Calmini lift and after talking & riding with them they have been very pleased with the kit & the performance. IMO the kit has all the essentials, the components are high quality, heavy duty, and the Calmini support/customer service is 1st rate.
FYI review is available at:
http://www.4wdandsportutility.com/archives/tech/0801_tech02.shtml The one option I would like to see from Calmini regarding their kit is a choice of shocks or not which I hear is going to happen at some point? While the bundled shocks made by Tenneco and comparable to rancho 5000's like what AC offers in their base kit are an improvement over stock, Bilstein's would be a better choice IMO.
From what I've seen/heard almost everyone has been satisfied with their choice of lift kits or components and they all seem to be happy with the extra clearance and performance. While there obviously differences in what's included such as the shocks, options, ease of installation, or price it really boils down to which one best meets your requirements?
Good luck and let us know how things work out
