Overall I'm happy with them. The ride quality out back is smooth, the springs have good travel and most of all they were cheap ($75 for the pair plus paint I think?). Some things to look out for:
-Even with the 7 wraps you're going to get some rake unless you do a big lift out front. I did tundra billies on the second perch with the stiffer old man emu's out front which gave me right about 3 inches of lift. As you can see in the photo there is probably 3.5-4 inches of lift out back and I haven't even installed that front plate bumper yet. I'll probably need to get some type of spacer for the front.
-The LC coils are MUCH taller than the factory springs which brings about two problems. First is that they are a PAIN to get in there if you don't have a second set of hands to push down on the axle.
-As for the second problem, replace the bolts holding the rear shock with sturdier hardware. The shock is only held on by the lower bolt and the taller spring puts more pressure on it causing the head to shear off (and the shock to dangle). I had to drill and tap to fix it...would have been the easiest thing in the world to just put new bolts in there off the bat.
All of this being said I'm happy overall. I think my biggest gripe about the lift kit I did is how stiff the emu shocks are out front. I'd recommend the LC rear springs to anyone looking for an inexpensive, high lift with decent road manners. Just be prepared to put in more wrench time than a bolt in kit.
