I didn't. The curvature of the plastic provides some structure. But now after a few years of use, the plastic is starting to get stretched and bent back. No biggy, but the waer edge gets extra wear on the ends due to the bending back.
I plan to find some time to redo it with some angle iron down there when I put on a new wear edge. Its pretty much used up (both sides as I flipped it a couple years ago).
