Welcome to the Best Lil Ole XFire Forum on the Net and congrats on your new ride !

A lil word of advise, use the search engine regarding questions you may have, if can't find your answer then post your question. Some folks here get a lil testy when the same question appears over and over

I'm not sure which bumper mods you refer to, may wanna try the technical and TSB section. Or I believe Allpar.com has TSB's on file. Hope that helps !

Welcome again !
