The guy who did all my welding is the head fabricator of the largest hearse and presidential limousine company in America. He actually wants to make them out of carbon fiber he's the same guy who is making my carbon fiber stator cover. This was my design and all of my cuts and measurements, the next one I have made will be a lot better and his welds pass DOT standards everyday for vehicle modifications I'm fairly certain these tig welds will hold up just fine id also offer a warranty if it cracks or breaks anywhere send it back to be fixed free of charge just pay the shipping.
