Swift Spec-R Sport Springs were engineered with 3 characteristics in mind.
1. Modified ride height compared to Sport Springs to maximize optimal suspension geometry.
2. Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicles factory shock valving.
3. Maintaining optimal comfort level for street use.
Spec R springs are wound with the same engineering and material as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.
