CUSCO Quality

It all started from "we love cars"

Since it's establishment in Gunma Prefecture in 1977, Carrosser's motto has always been: "Making quality needed by us and satisfied by us."

Developed in-house.
Rapidly improving.

We are continuing research and development every day with the aim of creating products that are faster, safer, and more comfortable. For the past 30 years or more, we have created original products developed in-house based on the ideas and knowledge of each employee. The crystal of such technology is a product called "CUSCO".

As a professional manufacturing group, we listen to the ever-changing voices of our customers and strive to collect a wide range of information. For this reason, we are working on an in-house integrated system from design to production, and are working to respond quickly with flexible ideas.

Practice makes perfect

Practice makes perfect

We believe cars with difficult handling don't run fast. It's the same for motorsports and on the street. We believe that machine settings that allow the rider to control with ease and without stress will bring speed and enjoyment to driving.

Carrosser participates in Super GT, Rally, Dirt Trial, Gymkhana, and other motorsport events with our in-house developed parts. We repeat rigorous performance and durability tests in extreme conditions—the end results are high-reliability and high-quality motorsport products.

Rigorous and relentless tests

Rigorous and Relentless Tests

Our in-house developed products, such as suspension kits and body reinforcement parts, are carefully simulated by ANSYS's strength analysis system. In addition to live tests, the suspension kits are subjected to a high-concentration salt spray test that complies with JIS.Z2371 in order to prevent rust adhesion.

Carrosser products are made with manufacturing tools and methods that have passed these rigorous tests.

Your needs are also ours

Carrosser's motto derives from producing quality aligning with our own needs and satisfactions. Carrosser's unchanging DNA is product development from the user's perspective, including from our staff who participate in races. In addition, our staff and demo cars visit dealers and events around the globe where we listen to direct feedback from our users for further improvements and enhancements.
