In 2002, famous suspension and exhaust maker JIC decided to participate in Drift D1 Grand Prix as a parts supplier and we have tuned the engine of the racecar.
We put exactly the same engine as our street complete engine "DERIVE" phase2 to the racecar and tested the engine at the same time.
We finally managed to win the long-desired 1st place, in round 5 at EBISU circuit.
We feed back the gained data through the racing to our products to keep the extreme quality.
