These springs are engineered with two main characteristics: 1) Redesigned lowered ride height to maximize the suspension performance, allowing the vehicle to fully absorb road condition for maximum traction. 2) Increased spring rate to further enhance cornering speed through entry \u0026amp; exit. The increase in spring rate is based on the vehicle's factory valve settings. Spec-R Sport Springs are increased to the optimal rate that the stock shocks can handle. Higher performance shocks are not required, but recommended for additional performance gains.\u003c\/div\u003e\n\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eSwift Spec-R Sport Springs were engineered with 3 characteristics in mind.\u003c\/span\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003c\/span\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eModified ride height compared to Sport Springs to maximize optimal suspension geometry\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eFurther increasing the spring rate to enhance overall performance.
