Hello there :)

I was just wondering if any one has experienced the rear bumper to be loose/saggy?
Ive just installed an S4 euro bumper, tightned the 4 bolts on the trunk and popped the bumper into the clips at the side.

But still the bumper is wery shacky and loose at the rear end, i can move it up and down about 5mm atleast.
the stock bumper was tight and nice so im doing something wrong..

any ideas? :)
