RS-R Coilovers - Sports-I: Spirited weekend track drives do not have to sacrifice daily driving comfort or performance. Designed for the performance enthusiast in mind, the RS-R Sports-I coilover system provides a comfortable ride for everyday use, yet is sufficient enough for those effervescent track days.

Why spend all day at the track dialing in your suspension when you should be on the track enjoying the experience. Damper and camber adjustments should not be a definitive factor, nor should you spend all day adjusting your suspension settings at the track. Drive to the track, on the track and drive home in comfort. Enjoy driving again with the RS-R Sports-I coilovers.

Racing Studio-R or RS-R began life as a wholesale distributor in Osaka, Japan. Unsatisfied with the quality of parts we were able to obtain, we started our own factory in September 1980. We strive to create only high-performance/high-quality products that do not exist in offerings from other companies. We do that by actively embracing the trial of motorsports competition such as drag races, N1, sprints, drifting, rallies and Super GT.

Now we are in the 21st century, where the social climate and technological innovation changes quickly. We want to pursue what our customers need, and what is best for society. In order to do that, we are committed to develop and manufacture products that satisfy the demand of our consumers now and in the future – without forgetting our beginning through the best technology and service.
