The Swift Spec-R Lowering Springs for the 2013-2018 Ford Focus ST (MK3) address the ST”s notorious wheel gap while adding the handling precision that Focus ST owners crave. These MK3 Focus ST lowering springs deliver an approximate 1.0″” front and 1.0″” rear drop with spring rates of 4.5 Kg/mm front and 5 Kg/mm rear, tuned to work with the ST”s factory sport suspension. Built in Japan from Swift”s proprietary material, these Focus ST springs reduce body roll and improve corner entry speed while maintaining the compliant ride quality that makes the ST a great daily driver.
