RSR Coilovers and Springs

Founded in Japan in 1980, RS-R has become a prominent name in the automotive aftermarket industry. From drag racing to drifting and circuit racing, RS-R’s products deliver exceptional quality and performance for both street and track enthusiasts. The name stands for Racing Studio-R. RS-R started out as a Japanese parts distributor in Osaka, then built its own factory in 1980 after deciding the parts on the market weren’t good enough, and that same standard has since carried through N1 endurance racing, sprints, and Super GT as well.

Every RS-R coilover is hand assembled, with laser-cut upper mounts, hand-welded lower brackets, and valving set by hand for the specific vehicle it’s built for. Urethane bushings and silent roller bearings cut down on the vibration and noise that stiffer aftermarket suspension usually adds to daily driving.

RS-R’s coilover range spans Basic-i, Black-i, Sports-i, Best-i and Best-i Active, so there’s a clear step up in adjustability as you move up the lineup rather than a single one-size-fits-all kit.

At Springrates, we are proud to offer a comprehensive range of RSR suspension products, from RS-R coilovers to RSR lowering springs and more. Each is meticulously designed and tested on actual vehicles to ensure optimal performance, ride quality, and handling.

RSR Lowering Springs and Suspension Kits

RS-R backs its coilovers with three dedicated lowering spring options: RS-R Down, Super Down, and Ti2000 Down.

RSR Down springs give a mild drop while keeping most of the factory ride comfort, and Super Down springs go lower for a more aggressive stance and sharper cornering, at some cost to ride comfort. RSR springs hold a consistent spring rate over the life of the part instead of sagging the way cheaper coils can. 

For a full suspension refresh, RSR suspension kits pair those springs or coilovers with sway bars and control arms, so the whole setup is tuned to work together instead of mixing parts from different sources. RS-R also makes Sig-Con damper warning cancelers for the small number of newer vehicles where lowering the factory adaptive suspension would otherwise trigger a dashboard warning light.

FAQs

What’s the difference between RS-R coilovers and standard suspension?

RS-R coilovers combine adjustable springs and shocks in one unit, allowing you to fine-tune ride height and damping. Standard suspension lacks this adjustability, making RS-R coilovers a superior choice for customization and performance.

How does RSR suspension improve handling?

RSR suspension enhances stability by lowering the car’s center of gravity, reducing body roll, and providing better responsiveness. Whether for daily driving or racing, RSR suspension ensures sharper cornering and improved control.

Are RSR lowering springs good for daily driving?

Yes. RSR lowering springs are engineered to balance comfort and performance. They reduce wheel gap, enhance stance, and improve handling without sacrificing ride quality, making them suitable for daily use.

What’s included in RSR suspension kits?

RSR suspension kits may include coilovers, springs, sway bars, and control arms. They’re designed to deliver a complete performance upgrade tailored to specific vehicles and driving styles.

What makes RSR performance parts different from other brands?

RSR performance parts are developed with motorsport expertise and tested on actual vehicles. Their advanced materials and engineering deliver superior durability, precision, and long-lasting performance compared to many competitors.

How do RSR springs compare to lowering springs from other brands?

RSR springs are manufactured with strict quality control and advanced materials to ensure consistent spring rates and long-term reliability. Their balance of comfort and handling often outperforms generic lowering springs.

What are RSR down springs?

RSR down springs are specialized lowering springs that reduce ride height while maintaining suspension travel. They’re ideal for enthusiasts who want a sportier stance and improved handling without switching to full coilovers.

Are RS-R coilovers adjustable?

Yes. RS-R coilovers allow adjustments to ride height and, in many models, damping. This flexibility makes them perfect for tailoring your car’s suspension setup to both street and track conditions.

Do RSR coilovers work for racing applications?

Absolutely. With their motorsport heritage, RSR coilovers are designed to perform under high-stress conditions like drag racing, drifting, and circuit racing. They deliver precise handling and stability at high speeds.

Do I need professional installation for RSR suspension kits?

While some experienced enthusiasts may install RSR suspension kits themselves, professional installation is recommended to ensure proper alignment, safety, and maximum performance.
