There are actually 3 drop spring kits for the WJ. Here are their specs:

Eibach: 1" front - 1.3" rear
H&R: 2" front - 1.8" rear
Groundforce: 2" front - 2" rear

The choice is yours...all depends on what you want...I have Eibach's on my WJ and really like them...I have thought about going lower.....but I dunno...lol...

As far as tires for a 18x9...I would say like a 265/60/18 or a 275/55/18....

What kinda wheels are you looking at, got a pic?

Those would look pretty cool..just make sure you have the right bolt pattern, and offset...dont' want those bad boys to stick out...unless thats what you want...
