RS-R 2013+ Lexus GS350/F-Sports (GRL10) Best-i Active Coilover

This is the RS-R Best-i Active Coilover system, specifically designed for the 2013 and newer Lexus GS350 and GS350 F-Sport models with the GRL10 chassis code. This system replaces your factory suspension components to give you a fully adjustable ride height and damping control, allowing you to fine-tune your vehicle's stance and handling characteristics. The 'Active' designation means this system integrates with your car's factory electronic damping control system, providing advanced adjustability without sacrificing modern convenience features.

RS-R has built these coilovers with performance and durability in mind. They feature a full-length adjustment system, meaning you can lower your vehicle significantly while still maintaining adequate suspension travel. The damping force is adjustable at each corner, allowing you to dial in the perfect balance between a comfortable ride for daily driving and firm, responsive handling for spirited driving or track use. The internal construction utilizes high-quality materials and seals to ensure longevity and consistent performance even under demanding conditions. This system is designed to work seamlessly with your Lexus's factory electronic control unit, so you won't lose the convenience of adjustable suspension modes.

When installing this coilover system, it's important to have your vehicle's alignment checked and adjusted afterward to ensure optimal tire wear and handling. The kit includes all the necessary components for installation, but professional installation is recommended for those unfamiliar with suspension work. You'll notice a substantial change in how your GS350 handles, with reduced body roll and improved feedback from the road, all while retaining the ability to customize your ride height and damping to your exact preferences.
