Follow up to manvelmk's inquiry. I eventually purchased the authentic Kuruma Z and Chargespeed bumpers through ConceptZ Performance. The authentic Chargespeed rear bumper fit almost perfectly right out of the box, however, some work was needed to get the Kuruma Z to fit properly. Also, the Impul side skirts required considerable customization to get them to fit to OEM quality and flush the the body. Hope this helps.

I actually have not purchased the bumpers/sideskirts yet. They are on my 'to-do' list after I get my coilovers and suspension installed. I will be purchasing through ARCH Industries who is a vendor on G35driver and have several threads about their products. They are supposed to have better fitment than the original molds and I can get them in polyurethane which is better than fiberglass. I received an estimate of ~$1200 for the Karuma Z front bumper, Impul sideskirts, and ChargeSpeed rear bumper (unpainted) I expect to have this project completed sometime middle of the year. There are others on the forum that have this same setup though.

Hey buddy, just read in your profile about your car, really nice setup actually.I have a question though, how much did your bumpers cost you. The kuruma z and the chargespead I mean, and how is their quality? If possible could you post some pictures of your car, doesn't have to be all hi res, just want to see how it looks. Thanks

Hey I noticed you were from Austin as well and just wanted to say hi. Also do you know of any g meets or are you in any? Would be interesting for us local guys to meet up and share some mods and stuff.
