Replacement M-Sport Air Dam

I recently purchased a 2003 540i M-Sport. The car is beautiful except for a dmaged air dam. I'd like to replace it with an original but I've heard that the replacement is not the same strength and thickness as the original. Does anyone know if this is true?

Thanks?

THanks....but I thought i was in the E39 section

You are, but the other forums I mentioned have a bit more model-specific traffic. Good luck!
