I am having some issues with the plastic underbody both under the engine bay and in the wheel wells.

the one in the engine bay has become detatched from my nismo front a few times and drags on the floor, very loud an obnoxious.

and now that I put spacers on my car my front wheels are rubbing against the plastic lining in the wheel well... if your looking at my driver side wheel its rubbing at around 10 o-clock

is it a bad idea to remove all of this plastic?

thanks

My skidplate came loose on the freeway and made a horrible noise. I took it to the dealership and they fixed it for free, seems a bolt came loose and fell off. Skidplate is pretty important in keeping crap out of going into the belt area.

^^Yea true. I'd be concerned with the belts and your air filter, especially if you have an open air filter like a K&N or JWT. I drove around with just the under body panel off for a while and my whole engine bay got dirty QUICK. If you can, I'd recommend repairing/replacing the plastic pieces.

It will cause TONS of debris to wind up in areas you wouldn't want it.. my suggestion ZIP TIE it down.. trust me, those little bolts fall off all the time, but zip ties work

That's exactly how mine is held on right now...

I've got mine held up with two zip ties to the bumper support. The best part is that when I need to remove the bumper there are no more little bolts to deal with.
