About Tomei

Tomei Powered USA Inc., established in October 2006, is an automotive performance tuning parts manufacturer based in Lake Forest, California. The company is 100% owned and operated by Axesta Inc., headquartered in Zama, Kanagawa Prefecture, in Japan. At the Japanese headquarters, all product development and control of manufacturing for the TOMEI brand are carried out.
The Japanese headquarters Axesta Inc., was established by former Tomei Powered Japan executives and engineers, led by Akira Sasaki, who served as CEO of Tomei Powered Japan for many years up until 2014, to produce world-class tuning parts that go beyond Japan’s limitations. With the rich experience of new members and continuous research and development, Axesta Inc. has successfully developed many high-performance and durable products. Axesta Inc. owns two brands: TOMEI and R.S.E. In the Americas and Europe, it operates as TOMEI “The Engine Specialist,” while R.S.E. “Real Speed Engineering” targets the Asian and Oceanian markets.
Before 2014, TOMEI was mainly developing products for the Japanese market with vehicle inspection restrictions in Japan. Now, Axesta Inc. has raised market standards to a higher technical level and is developing products that will meet high-end standards around the world. The products developed by Axesta Inc. aim to far exceed the regulatory standards in Japan.
Since 2014, Tomei Powered USA Inc. has been offering a wide range of top-notch tuning products, including internal engine parts such as crankshafts, connecting rods, camshafts, various valvetrain components, and head gaskets. High-performance exhaust parts include full titanium mufflers and stainless-steel exhaust manifolds, and peripheral parts such as ball bearing turbos, to name a few.
Axesta Inc., Tomei Powered USA Inc., and R.S.E. will continue to work hard and improve every day to help those who love tuning and racing.
