Started in Osaka Japan, our specialty has always been tuning and developing the performance parts for Honda vehicles. We also actively host track events for our customers and participate in several race series. All of our products and tuning menus are the fruit of the countless test and research on the actual race tracks and test courses. It has been our philosophy that only the products which meet or exceed the very high standard set by us are to be released to the market We believe it is this philosophy which results in the worldwide popularity of our products from the North America, Asia, Oceania, and Europe.
