The sources provide an extensive historical overview of the Japanese tuning house, JUN Auto Mechanic, focusing on its legacy of creating high-performance, multi-disciplinary vehicles. The first source details the story of the JUN Akira Supra, a legendary yellow Toyota MkIV that became an icon of the JDM golden age by successfully blurring the lines between drift car, circuit racer, and land-speed record challenger, culminating in a 249 mph run at the Bonneville Salt Flats in 2001. The second source expands on JUN's overall portfolio, highlighting other notable Bonneville-conquering Nissans, drag-spec Silvias, and high-horsepower Honda FWD platforms like the "Lemon" Civic, emphasizing the company's commitment to producing cars that excelled across various motorsports disciplines using in-house engineered components. Both texts confirm that JUN, founded by Junichi Koyama and Junichi Tanaka, established a worldwide reputation for "no compromise" performance tuning that greatly influenced global car culture.
