Nope, but fakes won't fit so well, so have to send to bodyshop kawtim those loose parts, and for some owners, (like me) who don't like drilling holes into car body (ori use screws, clips and brackets. (fakes use rivets and drill holes into body.) No problem for now, but after a few years when you want to replace the bodykit, suddenly notice those holes for the rivets all rusted.
But as far as I know, there is no Mugen EG9 lip copies that look close to the original. Eg6, got.
Like I said, it's your car. The shops selling your bodykit come from one source only.. so if recommend other place also same, even the sample pictures are same lol.
