Bilstein 5100's what are the negatives?

i know, i was just kidding

 

i would get them if you wanted to lift your truck. i have researched lifts on here since june of last year. they are the a great way to lift your truck and are very affordable. i was going to put them on my truck, but am putting on a front bumper from cbi. i am going with icon's up front, 5100's in the rear. i had 5100's for the front, but was scared the extra weight was going to pull me back down. it seems that as you stay under 3", you are fine, when you go above that, is when you start pushing the envelope twords more issues. just baised on what i have read on here, and found out from members.
