guys, when a car gets hit from the back, does the plastic undertray thing break as well when the bumper breaks? b/c that happened and the shop got me an Ap2 rear bumper on and as i was driving today a friend noticed that on the freeway my bumper was moving and bending a lot. i checked, that plastic thing isnt on the bumper...do you guys know why? shoudl the shop have bought that and installed it as well? is it the same price as the ap1 rear bumper or more?

btw, the front bumper, there holes on the bottom where it connects to taht same plastic, the screws dont get tight b/c there is nothign to hold it. why is that? do i need those plastic screw things or is another thing missing there as well?

 

u need those metal clips for the front, and the rear they are 2 plastic clips on the bottom check if u have them.
