Product Description
Swift 4T919R Spec-R lowering springs are designed for drivers who want a lower stance and firmer suspension response without replacing the complete factory damper system. The matched 1.2-inch front and rear drop reduces the Supra's wheel gap while maintaining a balanced ride height.
The 4.8 kgf/mm front and 12.0 kgf/mm rear spring rates improve body control, steering response and stability during quick transitions. Swift develops its Spec-R line near the performance limits of the factory damper valving, making these springs better suited to spirited street driving and occasional track use than a purely appearance-focused lowering spring.
Is the Swift Spec-R Spring Right for Your Supra?
Spec-R springs are Swift's more performance-focused option. They use firmer spring rates and a more purposeful drop than a typical street lowering spring. They are a strong choice for Supra owners who prioritize handling response but still drive the car regularly on the street.
Drivers primarily concerned with maintaining the softest possible ride may prefer a less aggressive lowering spring. The final ride and clearance will also depend on the condition of the factory dampers, wheel offset, tire size and alignment settings.
