RS-R Best-i Coilovers Lexus IS350 F Sport RWD 2021

The DDS system does not function on current aftermarket shocks and coilovers, but the Best-i Active series retains these factory controls. Now the factory actuator can be used on an aftermarket coilover so the damping and control systems still function like normal.

What is RS-R?

Racing Studio-R or RS-R is globally recognized for its top-of-the-line high-performance suspension products for both daily drivers and the motorsports industry. RS-R began life as a wholesale distributor in Osaka, Japan. Unsatisfied with the quality of parts they were able to obtain, RS-R started its own factory in September of 1980 and sought out new ways to take driving to a new level of comfort with style and performance in mind. In 1998, the company established distribution in America and the rs-r.com website. In 2011, RS-R opened RS-R USA, their American subsidiary. They are continuously working to establish their brand and reputation in America.

What is Special about RS-R?

RS-R strives to create only high-quality and high-performance products that do not exist in offerings from other companies. The brand is world-renowned for its superior suspension and exhaust parts. RS-R achieves that by actively embracing the trial of motorsports competition such as drag races, N1, sprints, drifting, rallies, and Super GT. 

In the 21st century, where the social climate and technological innovation changes quickly, RS-R continues to thrive through adaptation. The brand is dedicated to pursuing what its customers need, as well as what is best for society. In order to do that, RS-R is committed to developing and manufacturing products that satisfy the demand of their consumers now and in the future.

RS-R coilovers are specially designed to boost your driving experience. Each vehicle-specific product is precisely assembled with close attention to detail using laser-cut upper mounts and hand-welded lower brackets. RS-R utilizes modern urethane bushing technology and silent roller bearings to eliminate excess vibrations from everyday driving and minimize noises from suspension movement. The company’s superior selection of lowering springs are made for comfort and function, meaning they not only look good but perform incredibly well too.
