Ford's use of a novel casting process caused cracks in the GT supercar's control arms, reported last December, AutoWeek is reporting today. Rather than use forged parts, shaped by high pressure, the company touted a process by which parts are cast in molds using metal heated to the consistency of butter (holy "Last Tango in Paris" flashback). Back in December, inspectors had found cracks in some cars' control arms, and Ford asked all owners not to drive their cars until the company could replace the parts, considering that losing a control arm at 200mph could be nearly as harmful as the side effects of Vioxx.
