Product Details
These Swift Spec-R lowering springs fit the 2020+ Toyota Supra (A90).
They give the A90 Supra an approximate 1.2" front and 1.2" rear drop with spring rates of 4.8 Kg/mm front and 12 Kg/mm rear, matched to the Supra's adaptive damping and multi-link rear suspension. Built in Japan from Swift's proprietary H5S.TW spring steel, these Swift springs are proven in HPDE and time attack and reduce body roll.
