I went to the Silver Dollar quarter mile track and took my J30 for some runs. I talked to one of my buddies friends and he told me that he had a friend who told him that the "t" on the J30t stood for "turbo." When he told me this I busted out laughing:lol: and had to tell him that his friend was BSing him. Then I had to explain what the "t" really stood for "touring."
