Product Details
The Swift Spec-R Lowering Springs for the 2020+ Toyota Supra (A90) lower the A90 Supra's ride height to match its aggressive sports car styling while improving cornering grip and high-speed stability. These A90 Supra lowering springs deliver an approximate 1.2" front and 1.2" rear drop with spring rates of 4.8 Kg/mm front and 12 Kg/mm rear, tuned for the Supra's adaptive damping and multi-link rear suspension. Built in Japan from Swift's proprietary H5S.TW spring steel, these Supra springs are proven in HPDE and time attack, providing reduced body roll and the precise weight transfer feedback that makes the A90 such a rewarding platform to drive hard.
