For those of you who have installed the bomex kit, did you need to install some sort of front and rear stabalizer underneath to support your bumpers???? i know the stock bumper has the front under plastics and the rear bolts in underneath with screw clips, but the bomex kit doesn't have any of this. i already went out and bought some peices of aluminum to use as stabalizer bars, just wondering if i really need them to prevent the kit from cracking.
