Bro...

Need your genius advices regarding my body Civic EG9 i put EG6 Bumper, but the bumper seems like doesn't fit to the EG9 body kit cun2 la.... got gab like accident car... so i've dismantled the EG6 bumper and use back the original EG9 bumper...

But i've seen few time's people using it fit just nice like original, and why is that??? I wanted to stay and ask the owner, but some just say "entah" or i'm not able to locate the owner...

can someone please share with me on this...
