Well I have almost finished my subframes and all the bracing on my mustang. I am going to be making my own floorpans since the stockers will not fit. I was wondering what gauge thickness I should go with. With the new subframes, the actually floorpans will not be as much of a structual componet as they would be in stock form. I believe the stock floorpans are ~18gauge. I was thinking of using 20 gauge with beads rolled in them. Rolling beads in 20 gauge will be easier than rolling beads in 18 gauge. What do yall think, going with 20 gauge will offset a few pounds (~40 pounds).
