nope, and don't plan on it till i have an issue..
The stiffer bars will, well, stiffen up the front end.. All things considered, the bumper weighs less then a passenger would, so i just cranked them a little, to offset the drop (little over 1/4 inch) and off I went.. Once i have a winch installed, and the other skidplates.. I will see what the extra weight does.. After I put on the upper a arms, the spring loading should drop (just a little) sence the a arms will be rotated slightly down, and have less leverage at static ride hight.. as the lower arms pass the horizontal position, the leverage is max on the tbars..
