That is just like mine. Mine is also welded. I have a lot done to this car but most of it was completed by the last owner including this. So I can't tell you before and after. One thing I can tell you is that this E46M compared to my last one is on a whole new handling level. My wife is so annoyed with cornering in third at this point that she threatens to open the door and jump out every day now.
