Stillen GTR rear bumper cover

[VRtual boy]

Hello folks,

Does anyone have the Stillen GTR kit rear bumper cover
installed on their '98 200sx?  If so how did you keep
it from sagging?  The reason I'm asking about the '98
200sx is because it seems that the bumper cover wasn't
design to fit this model year.

Mine is sagging pretty bad on the sides.  I'm trying
to come up with ways to somehow pull it up so that it
is flushed with the rest of the body.  I was thinking
of using some sort of brackets to hoist it up.

Let me know what you folks think, I would definetly
like to hear some ideas.

Thanks everyone!
