RS*R Coil Spring Set

RS*R Coil Spring Sets: Japanese Precision Meets Performance Lowering

When it comes to aftermarket coil spring sets, few names carry the weight of RS*R (Racing Studio-R). Recognized as the number one aftermarket spring manufacturer in Japan, RS*R has spent decades perfecting the science of lowering a vehicle without sacrificing the ride quality that makes daily driving tolerable. Their coil spring sets represent the ideal entry point into suspension tuning — a direct-fit upgrade that transforms both how your car looks and how it handles.

A Spring Series for Every Driver

What sets RS*R apart in the coil spring category is the sheer depth of their lineup. Their current standard series includes the RS*R Down, RS*R Super Down, and RS*R Hard Down — each tuned for a specific balance of drop height and spring stiffness. Drivers seeking something more advanced can step up to the flagship Ti2000 line. The Ti2000 uses a titanium alloy of the highest quality and is designed to give the driver the maximum drop in ride height without compromising riding comfort. The Ti2000 series further branches into Ti2000 Down, Ti2000 Half Down, Ti2000 Super Down, Ti2000 Hard Down, Ti2000 Hi-Road, and Ti2000 Straight variants, ensuring there is a tuned option for virtually every combination of vehicle and driving style.

Ti2000 Technology: What Makes It Different

The Ti2000 is currently the only suspension coil using its proprietary titanium alloy technology. This advanced material approach has a direct impact on weight: due to the new materials used in the Ti2000, RS*R has been able to produce a highly durable suspension coil with a smaller diameter and fewer spring coils, reducing overall weight by more than 2kg. Less unsprung weight translates to sharper turn-in, better ride compliance, and improved overall dynamics. The Ti2000 also uses a two-part epoxy coating with excellent resistance against corrosion, and its hybrid polyester-epoxy finish provides strong protection against color fade.

Engineered for Your Specific Vehicle

RS*R Down Sus lowering springs provide a mild drop and improved handling, taking into consideration the factory suspension geometry, shock dampening, spring rate, and ride height levels to ensure the springs are made precisely for each vehicle, for both performance and comfort. The RS*R suspension coil range is available for a large number of vehicles and is a proven, easy, and effective way to lower a vehicle while maintaining ride comfort, with highly durable construction guaranteed to perform under harsh conditions.

Backed by a Serious Warranty

RS*R stands firmly behind their coil spring sets. The RS*R Down, Super Down, and Hard Down series include a manufacturer warranty of 3 years or 50,000 km against spring fatigue, while all Ti2000 Series springs carry a Lifetime Warranty against spring fatigue. That kind of coverage reflects the confidence that comes from over four decades of suspension engineering in Japan.
