Ok heres my problem. I have a 92 318is and the rocker panel right behind both front wheels has rusted and needs to be replaced. My question is Should I have the rocker panel fixed(new metal welded in and painted), or do I buy M3 rockers from TMS.Are the rockers from TMS metal or plastic? Do they come painted? Anyone had the same problem with rusting behind wheel wells? Can the rockers can be removed from the body? Any suggestions are much appreciated. This group has been a great help in the past. thanks in advance
