Just ordered the last BMW structural foam in stock for the subframe reinforcement from Mike @ bmwpartstore. All I need now is seam sealer, mega's injection gun, a drill bit, and some nerves of steel as I undergo this intimidating project. Fairly simple but I don't want to waste $200 worth of foam :/
BMW part# 83190445721
I also hope no cracks had developed from the last time i "checked" the subframe area until now (couple months??)
