Ive noticed that Honda has a fascination with underbody panels. When I installed the Beatrush rear performance bar I noticed that the underbody panel does not sit flush with the new performance bar. Is there any purpose to the underbody panels that are installed on the car. The only thing I can think of is aerodynamics and better fuel economy and possibly keeping the underbody dry. Thye car seems to be making a lot of creeking noise since the beatrush parts installs and I think it may have something to do with the rear underbody panel not sitting flush since I could not secure it all the way. I might just remove it when I install the front aluminum underbody panel if it doesn't harm anything.
