E46 Subframe solution (PIC inside!)
I have been looking for a way to reinforce the rear subframe without welding anything.
The way I see it, is that when you weld the reinforcement plates in, you burn the paint and any sealant off on the other side of the floor panel. Normally this wouldn't be such an issue however the floor in E46s is double layered which does not allow you to properly paint and seal the weld area on the inside. This will lead to rust and weakening of the subframe in the long run.
So...I set out on a search for a solution, here is what I found...
EDIT: more pics and instructions added on page 4
I wonder how it attaches to the floor. Hope it's bolted up like the rest of it.
