Hey guys! For those of you that are asking how the fitment on my Lip + Fang Cover combo worked out, it's hard to say.
The issue with the 3-pc lip is the center. It's designed to rest inside the recess with the fangs. So if you have the fang cover, it pushes it forward, and then throws everything out of alignment, where the front sticks out too far. I had to grind the side tabs on the center piece, and to make it all fit together seamlessly, I used black silicone from home depot to kind of "3d mould" the lip together. It actually came out nicer than I thought, and I get compliments all the time about it!
My original plan was to have a shop mould it together nicer, but this way - I'm not committed to the lip - it's still removable and can be sold and used on a regular 370z without the fang cover, and I think the black silicone is unnoticeable unless you look closely. It's no pro job, but it's good enough for me. I'm planning on Amuse down the line, so.
