RS-R 2021+ Lexus IS 300/350 RWD (FSport RWD) Super Down Springs w/ Custom Bump Rubber (2pcs) - T591S
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.
