Legendary street racer Kei Miura changed the Japanese tuning scene when he introduced the Rocket Bunny parts, exclusive bodyparts to change the look of cars that he began crafting in his shop, in cad, after scanning the cars. This lets him produce high quality parts in weeks, compared to manufacturers that work directly on the car or on models.
He is fully self taught - and says few people used cad for 30 years like him - he began making rides for Disney Tokyo.
