the ones in the wheel arches are gone on my car i lost one in a drifting accident, as well as the the front bar the to create symetry i ripped the other one off.. nice.
my whole front end used to be zip tied on, imagine what the world would have been like without zip ties... terrible.
seriously though i put the new front bar on and i haven't worried about the wheel arch gaurds and i have had no issues for 4 months or so.
