hi there, you know i am a hardcore fanatic of gan san but he didnt do this lap time, check the video, the driver uses glasses, plus, the helmet, is different from the one that gan san usually uses. (gan san uses this helmet that let your face uncovered, he used a full closed helmet in a test drive of the s2000 around suzuka, thats the only time i saw him with a helmet like that)
the point is, the driver is takashi oi or takashi ohi (i dont know what is the correct way to writte the oi/ohi since it appears in both forms from different sources.
i hope you correct this because i think that guy deserves the credit.
