I had it installed for awhile, but I just noticed that

The lip kit was little off in the middle. I could see a tiny gap between where the lip is to my car in the middle, everything else is attatched fine. Is there way you can adjust so that everything is firmly attached? It doesn't move around like or anything but it feels like when I wash the car the wat probably will get under lipkit, and I don't think that would be a good thing. Does everybody expereince this?

 

Are you talking about the Nismo front lip?
If so, they include some washer in the hardware kit. The instructions explained that they could be used to pull the lip in tighter if necessary.
I didn't need them.
