custom backspace rims (wheel vintiques says nope)

Well, i was excited about my new rims from Art Bair Wheel until I went to get them mounted and balanced today and they are warped all to heck. not usable at all. I messaged Art and sent him videos of it wobbling on the balance machine and he made every excuse in the book to not own up to it, including blaming UPS for what would basically require someone over there taking a sledge hammer to them.....so he makes money and gives me back unusable rims. now i get to look for a place to straighten them out....if they even can be. use Art at your own risk.
