! As an aside... I work for Hitachi Automotive Products in Ca, and several of our (older) engineers were excited at my recent aquisition. They extolled Hitachi's role in the Z car. One in particular, however, stopped short about praising the Hitachi SU's on the car originally.
"They were not so great." He later admitted in private... away from our Japanese executives!
Definately not information related to Suspension components, but your post reminded me of the conversation!
