I have a RE version and it is about to get painted. How do i take the sag out of the bumper?

 

I was told, and I have the Mazda '99 Spec, not the Rotary Extreme or RE Amemiya and I've never seen sagging. Since it's Polyfiber... (Poly Urathane and Fibre Glass) and together they don't sag... I've been told...

But someone in the industrial business might be able to confirm or deny this better than me....

 

I've had my 99 spec front bumper on for around 4 years, no sag whatsoever.

 

i dont think the original sags...only the copies

 

Glue some thin styro foam strips against the inside of the bumper where you think its gonna sag and fill it in little bit with low expanding foam. Therefore the styrofoam protects it from pushing up in just one area...but will prevent it from sagging.
