mine weighd about 20lbs on my 2012rcsb. dont notice much difference in the corners either. im used to sportier cars so my truck has always sucked to me in the corners.

 

Mine is gone. Didn't really notice any difference driving. It's worth pulling it off to ditch some weight!

 

A month and change later update. Still have it off the truck feels good. I live in WA and drive 30 miles to and from work half city half back road. No major draw backs truck does wallow a little but not to bad the HD shocks help control a lot of that. Its not to bad at all. The truck transfers weight fairly well doing roll races and digs the truck pushes down hard and lifts up the front not off the ground just noticeable movement. Not to bad. Worst case if I don't like it in a few months then put it back on.
