Enhance the performance and appearance of your 2023+ Nissan Z with the Swift Spec-R lowering springs. Designed specifically for the RZ34 chassis, these precision-engineered springs provide an approximate 28 mm (-1.1”) drop at all four corners, improving handling response, chassis balance, and stance without sacrificing ride comfort. Swift’s exclusive HS5.TW alloy and advanced coil-winding process deliver superior strength, reduced unsprung weight, and consistent performance for both street and track use.

• Improved stance & balance: Lowers the vehicle evenly to reduce wheel gap and lower the center of gravity for sharper turn-in and more stable cornering.
• Proprietary HS5.TW steel alloy: Lightweight yet extremely strong, ensuring minimal sag and precise response through repeated compression cycles.
• Motorsport-derived design: Developed through Swift’s extensive racing experience to provide crisp feedback, improved control, and faster transitions.
• Optimized ride quality: Offers responsive, predictable handling while maintaining comfort for daily driving and spirited runs alike.
• Direct fitment: Designed for the Nissan Z RZ34 platform; compatible with OEM and most aftermarket dampers—no modifications required.
