Before that, the previous record was 264.71km/h by a Trans-Am so it was a huge leap forward. That was a landmark achievement and became the benchmark for all the street racers and tuners to beat. Together in 1981, they were the first in Japan to officially go over 300km/h (307.69km/h, at Yatabe). The person who tuned his car was none other than Masaru Hosoki from ABR, one of the most famous Japanese tuners and also NASCAR skilled Mario Rossi helped. He used a DeTomaso Pantera with a chevy V8 in it. In the early 80s, he was famous for his top-speed runs.
