So i have a idea of what it is but can somebody explain it more and i do autoX and should i get the DTSS eliminator bushings.

 

well, you haven't given any information as to what it is YOU think it is, so it's hard to explain it MORE. for all i know, you know more about it than i do.

anyway, if we dial it back to the late 80s, there were a few manufacturers that experimented with and even released 4-wheel steering systems. included were Nissan, Honda and yes ... Mazda, to name a few.

DTSS as i understand was more of a pseudo-4WS system though, or maybe better referred to as an "active" suspension system. basically the rear suspension on the Rx-7 would automatically adjust rear camber and toe during cornering.
