About RS*R: Precision Suspension Engineering

RS*R has built a devoted following among performance driving enthusiasts by doing one thing exceptionally well: engineering suspension components that transform the way a car feels on the road and the track. With North American operations headquartered in Anaheim, California, RS*R brings decades of Japanese suspension development expertise to drivers who demand more from their vehicles than factory settings can provide.

The brand's philosophy centers on the idea that a car's suspension is its most critical interface between driver and road. Every spring rate, every coil diameter, and every damping characteristic is developed with real-world driving conditions in mind — whether that means a daily commuter that needs a sportier stance without sacrificing ride comfort, or a dedicated track build pushing hard through corners. This obsessive attention to detail is why RS*R has earned consistent respect in enthusiast forums, import car culture, and the broader performance aftermarket.

RS*R Coil Springs & Lowering Solutions

The heart of the RS*R lineup lies in its spring products. Their coil springs are engineered to deliver precise spring rates that improve handling response while maintaining a predictable, controlled ride. Unlike generic lowering solutions, RS*R springs are application-specific — developed and validated for individual vehicle platforms so fitment and performance are dialed in from day one.

For drivers looking to upgrade both front and rear handling in a single purchase, RS*R's coil spring sets offer a matched pair approach that ensures balanced chassis behavior. Using a complete set eliminates the guesswork of mixing components and helps preserve the intended handling balance the engineers designed into each vehicle platform.

When a more aggressive drop is the goal, the RS*R coil spring lowering kits deliver a meaningful reduction in ride height alongside improved cornering geometry. A lower center of gravity reduces body roll in corners, sharpens steering response, and gives any vehicle a purposeful stance that looks as good as it performs. RS*R lowering kits are designed to work within safe ranges that keep suspension geometry intact — a critical detail that separates quality lowering solutions from cheap alternatives.
