my bumper is binding when laid out???? HELP!

I drilled out a hole in the back part of the Z and put bumpstops on em. it still lays out really hard and the bumper doesnt really bind anymore...but yeah I think we DID z the front end to much...oh well

I never had any issues on mine with the bumpers, but my fender and door gap closes up at the bottom when the truck layes out on both sides ,and opens back up when I air up. I shimmed the bottom of the fender out a bit so the door didnt hit, but it still does it, only thing I can figure is frame flex, and something is stressing when it lays.

just trim the bumper with a boty swa or if you have a band saw you can get a better cut
