Just an FYI the spring heights are going to be the same between the different models ie Rubicon, sahara, sport. The only difference is spring rate which may be 1/4" - 1/2" at most in spring height.
The only place I could see a difference would be 2 door versus a 4 door but I would imagine they are similar.
If I can find someone with a stocker I will throw a tape on it for you though.
