Product Details
The Swift Spec-R Lowering Springs for the 2015-2021 Subaru Impreza WRX (VAG) give your VA-platform WRX a lowered stance and sharper handling response that matches the car's turbocharged performance. These WRX lowering springs provide an approximate 1.0" front and 1.0" rear drop with spring rates of 6 Kg/mm front and 7.2 Kg/mm rear, designed to work with the WRX's MacPherson strut front and multi-link rear suspension. Built in Japan from Swift's proprietary H5S.TW material, these Impreza WRX springs reduce body roll under hard cornering and improve traction during aggressive launches on both street and track surfaces.
