I have that exact kit on my car and I love it... I use to have the H&R Full coilover kit and I changed to this setup and have liked it better... You have soft/hard adjustment on the struts themself, also you'll have a starting height to choose from on the bottom of the strut... custom spring rating on the Ground Controls as well as I beleive 4" or adjustment there... You're overall ride quality (bumpiness) will determine what spring rating you get... I have a really stiff spring setup so my car is very tight and firm (yet not logging truck bouncey though)...
