I've been using some leftover carpet pieces for mats for as long as I can remember. Constantly bunching up under the pedals and hard to keep clean. I found a rubber utility mat at home depot, and decided to cut it to fit. Looks real good. I'm using it with the pattern side down and it grips the ff5 carpet pretty good. Almost can't tell that they're in there. $28 for a 36"×48" piece.
