Swift Spec-R Sport Springs were engineered with 3 characteristics in mind.

• Modified ride height compared to Sport Springs to maximize optimal suspension geometry
• 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
• Maintaining optimal comfort level for street use

Swift's Spec-R Springs leverage proven spring technology with elevated stiffness and refined geometry tailored for circuit performance. Engineered to the threshold of factory shock capacity, these springs deliver track-validated handling without sacrificing street usability. The same material science and winding precision as Swift's sport line ensures durability and consistency, while the aggressive rate and modest ride height adjustment maximize suspension response. Ideal for drivers balancing weekend track days with daily driving demands on the F82 M4.
