There were many RX-7’s on hand the other week at Tsukuba Circuit; all in a fierce battle to claim the quickest lap around Tsukuba’s 2 mile stretch. The battle of the tuner’s unfolded throughout the day, as various time attack builds shot their way around the 14 corners of the circuit at top speed. Among them was the Arios Okuyama Auto Sports FD3S. This purpose built machine was among those in the dogfight on track, and surprisingly enough, did quite well against the heavy hitters – managing a best time of 58.818. JDM Clips was on hand to get a closer look at this build. Click past the break to see more.
