RAYS  participates in all categories of races that exceed the competition level, as well as the highest peak races such as the F-1 and GT1 World Championships. Now, the place of activity is not limited to Japan, but also actively participates in races in the United States and Europe.

Racing is the forefront of development that is indispensable for Rays, and above all, it is a place for serious competition. Rays believes that the race where everyone on the spot goes for the win is not deceptive, and putting yourself in a place where only the real thing remains can improve the performance of the road wheel.
RAYS has won titles in many categories, but it's not just about winning. The most important thing is to gain the experience and know-how of racing for one second of commas and prove the correctness by winning.
At the wheel development site, there is now almost no line between computer and field testing, and the results are almost the same on the computer. Experience is the key to this. The numerical values ​​that computers tell us are due to the data we have experienced and accumulated. It is just the result that appears on the screen through a filter called a computer. However, with the constantly updated data, it is not impossible to build even the wheels that we thought were reaching their limits, even lighter and stronger.

And that know-how is not limited to the category of sports wheels, but is equally distributed to all RAYS wheels. The know-how to gain lightness and strength is utilized not only for forged wheels and cast sports wheels that claim high performance, but also for dress-up wheels that decorate the feet of sedans and minivans. To that end, we will stubbornly protect our own development and production, and above all, Made in Japan. This is the meaning of "concept is racing" that Rays advocates.
