soon as i put my coilovers on it came off lol....kept scraping....i havent personally noticed a diff...

 

only a few people here knows the importance of the undertray. I left mind off for a week and I noticed a difference when crusing high speed 120mph+, I felt more resistance as i tried to go faster...

Trust me it's there for a reason, that's why you see ferrari they have flat bottom panel all over. For those people who said there is no ill effects, they don't know what they are saying, if you are lazy to put it back, get the Beatrush one, it's really nice piece.

 

I still have mine but I have cut a piece of it in order to fit my turbo XS FMIC.

 

No doubt it helps, but really where do you find room to CRUISE at 120 in jersey? Lol i'm originally from rutherford by giants stadium and yes i'd occasionaly hit 120+ but not for long. Not long enough to enjoy all the benefits of a pain in the butt oem tray. In my eyes, it's either a nice tray like beatrush or nothing. And if i daily drove my car beatrush it would be . And no i'm not kissing their a$$ it's just the unit i'll buy when it comes down to it.
