During the Race Wars scene when Jesse was just getting to his car for his race against Johnny Tran, Johnny Tran pulls up and rolls down his windows. When the windows roll down, Tran is clearly wearing a black long-sleeve shirt in the next two or three side shots of him. But, the first frontal shot of Tran shows him wearing a black tank-top. He is wearing that tank-top all through the race and in his fight w/ Dom.
