You know, I was thinking about it. Is it possible they sent you the wrong model bar? Maybe they sent you a WRX bar or something and packaged it incorrectly in the warehouse. That would explain the poor fitment. I have a Cusco sway bar, X brace, had Cusco suspension and sways on my FD RX-7, etc...I have never had a problem with the fitment or performance of their products. This is odd. I think it might just be the wrong bar. I would take it back and get another.
