Product Details
The Swift Spec-R Lowering Springs for the 2014-2019 Ford Fiesta ST turn Ford's pocket rocket into an even sharper handling machine with a lower stance and reduced body roll. These Fiesta ST lowering springs deliver an approximate 1.1" front and 1.0" rear drop with spring rates of 3.8 Kg/mm front and 3.8 Kg/mm rear, specifically tuned for the FiST's lightweight platform and torsion beam rear. Built in Japan from Swift's proprietary H5S.TW high-tensile spring steel, these Fiesta ST springs are popular with autocross and rallycross competitors who rely on the FiST's go-kart-like agility and need springs that keep up with aggressive driving.
