Matt, the front end of my Z are basically three parts:
Two of them are EVO-r overlays. Here's the EVO-r website -
EVO-R INC. Nissan 370Z Z34 Performance Parts
The parts I have are the Carbon Fiber Center Bumper cover and Carbon Fiber Front Bumper Top cover.
The final part is a Mine's front lip -
Mines Front Lip
I did have the lip molded to the stock bumper and I had the "fangs" removed and mesh put in the center. Send me a msg if you have any questions.
