Mine's

Mine's Co., Ltd. (Japanese: 株式会社マインズ, Hepburn: Kabushiki-gaisha Mainzu), or simply Mine's, is a tuning firm based in Yokosuka, Kanagawa Prefecture, Japan.^[1][2]

Mine's was started by Michizo Niikura in 1985. It attracted attention in 1988 with the debut of its VX-ROM ECU module for the Nissan R31 Skyline GT-R,^[3] being among the first Japanese companies to sell reprogrammed ECUs for Japanese sports cars. Mine's currently sells VX-ROMs for hundreds of Japanese cars, but only produces hardware upgrades for a few select cars.^[4] The latter includes exhaust systems, engine internals, suspension parts, brake systems, and carbon fiber body parts.^[1][5]

Mine's is also known for its work on the Nissan Skyline GT-R—specifically the R32, R33, and R34^[5] models, as well as the Nissan R35 GT-R.^[1] Aside from the Skyline GT-R, Mine's also sells upgrades for other cars such as the Mitsubishi Lancer Evolution,^[4] the Subaru Impreza WRX,^[4] and the Nissan Fairlady Z.^[2] The Mine's Z is unusual because it remains naturally aspirated,^[2] unlike Zs from other tuners.

Mine's has also gained additional popularity through video games, most notably the Gran Turismo^[6] and Forza series.
