I believe papadakis car was also running the RX7 rack and pinion and power steering pump. I read somewhere that they called the guys at RSR for some tips while building the AEM drift car. It also said that the RX7 rack had a more significant amount of steering angle. They also removed the gas tank and put a custom fuel cell where the trunk is. Its funny cause in the article they kept saying that they were ruining a perfectly balanced car awesome for the track, but horrible for drifting.
