RS-R Superdown Suspension Springs Lexus IS300 | IS350 RWD 2021+- RS-R-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.

The Superdown provides a lowered stance and improved handling to fulfill your needs to lower your car and improve its handling. Taking into consideration the factory suspension geometry, shock dampening, spring rate and ride height levels, RS-R ensures that the springs you are getting were made for your car both for performance and for comfort.
