You could try a lot of shops, but ask to see some of their work before you go. Cue is a good place to go to if you live near 54, but there are some other shops.

Also, ignore all the posts about OMG BODYKITS ARE GAY, all people do on this site is hate on each others car. ZenkiS14 gots the Skyline front bumper on his car is it looks real good.

But word of advice now since cops are busting everything, get a tasteful kit that isn't too flashy.
