Description

The TEIN Premium SPEC Comfort Sport Coilovers (part number GSL90-K1SS3) are engineered to provide a balance of everyday ride comfort and sporty handling. Developed by TEIN, these coilovers are designed as a direct replacement for your vehicle's factory suspension system. These coilovers feature adjustable damping, allowing you to fine-tune the suspension to your driving preferences, from comfortable daily commuting to spirited driving. The "Comfort Sport" designation indicates a focus on improving the ride quality while enhancing handling characteristics. Installation involves replacing the original struts and springs with these new units. For optimal performance and longevity, it is recommended to have these coilovers installed by a qualified technician. Compatibility is vehicle-specific; please verify fitment for your exact make, model, and year before purchase.
