RS-R Coilovers

RS-R is a legendary Japanese suspension brand, known for lowering springs and coilovers that deliver an aggressive stance with real-world usability. At Springrates we carry the RS-R coilover range, including the Sports-i, Black-i, and Best-i lines.

Japanese-Engineered RS-R Coilovers

RS-R has a deep motorsport and street heritage in Japan, and its coilovers reflect that blend of aggressive stance and tuned ride quality. The kits offer height and damping adjustment with valving developed on Japanese roads and circuits, giving you that signature low, planted RS-R look without a punishing ride.

The RS-R Coilover Lineup

The Sports-i is the street-and-track kit, offering adjustable damping and a great balance of stance and comfort. The Black-i steps up the spec, and the Best-i range covers everything from comfort-focused to hardcore setups, including the Best-i Jouge. RS-R also offers its famous Down Sus, Super Down Sus, and Ti2000 lowering springs for a simpler drop.
