Description

The K-Tuned Spec-R Lowering Springs are specifically engineered for the 2009–2020 Nissan 370Z Z34 chassis, aiming to enhance both performance and aesthetics. Key specifications for these springs include a front spring rate of 10.0 kgf/mm and a rear spring rate of 10.5 kgf/mm. This setup results in a front drop of approximately 1.2 inches and a rear drop of approximately 1.0 inch, visually lowering the vehicle. These parameters are carefully balanced to maximize suspension performance and optimize geometry. Swift Spec-R Springs are built to provide an ideal balance between track capability and street comfort. Their design prioritizes enhanced steering response and a lower profile for a more aggressive look, making them suitable for drivers seeking improved handling without sacrificing daily drivability.
