SWIFT SPRINGS 4T914R Swift Springs 4T914R Spec-R Suspension Spring Kit for Lexus RC F, Front and Rear

Upgrade the handling and stance of your Lexus RC F with the Swift Springs 4T914R Spec-R Suspension Spring Kit. Designed for 2015–2026 Lexus RC F models, this vehicle-specific kit includes lowering springs for both the front and rear suspension, helping create a more purposeful appearance while supporting responsive street and performance driving. The Spec-R system is engineered as a complete spring solution for enthusiasts seeking improved suspension performance without selecting separate front and rear components.
The springs are manufactured from durable steel and finished with a black powder coat for a clean, understated appearance and added surface protection. The application-specific design is intended to work with the Lexus RC F platform and provide a properly matched setup across all four corners. By lowering the vehicle’s center of gravity, the kit can help promote more controlled body movement during cornering, braking, and acceleration while maintaining a balanced driving experience.
Swift Springs is known for developing performance suspension components with a focus on ride control, fitment, and consistent spring performance. The 4T914R Spec-R kit is a practical choice for drivers who want a sport-oriented suspension upgrade with a coordinated front and rear configuration. Verify vehicle year, model, and suspension compatibility before installation, and have the springs installed by a qualified technician using appropriate suspension service procedures. A professional alignment is recommended after installation to help maintain predictable handling and support proper tire wear.
