BS....there's plenty of Jeeps on this forum that are modified and lowered. Like tnadanzig, mine is lowered with Eibach SRT lowering springs. If you don't put the shorter inner cone in the rears, you'll bottom out big time, like I did at first. Now bottoming out is not a problem. If you put the SRT front bumper on, again like I did, it is low enough so you have to be very careful going up driveways, and running into cement parking stops in parking lots. Also, if you're in a moderate snow climate, I wouldn't recommend the lowering springs with the SRT bumper. Snow deeper than 4-5 inches on the road will cause you grief.
If you're mainly after making it handle like it's on rails, and live in snow country, I'd recommend you do the lowering springs, the SRT sways (again I used Eibach), and Bilstein shocks, with the stock front bumper. You'll love it for sure, especially if you like ~10X better handling than stock.
