The Swift Spec-R Lowering Springs for the 2005-2007 Mitsubishi Lancer Evolution 8/9 MR (CT9A) optimize the Evo”s already-legendary suspension geometry with a lower center of gravity and increased spring rates tuned for competitive use. These Evo 8/9 MR lowering springs deliver an approximate 1.4″” front and 0.8″” rear drop with spring rates of 6.4 Kg/mm front and 6.8 Kg/mm rear, designed to maximize the CT9A”s Bilstein damper performance on track. Made in Japan from Swift”s proprietary spring steel, these Lancer Evolution springs reduce unsprung weight and eliminate coil bind, providing the kind of precise suspension feedback that Evo owners demand for time attack, rally-cross, and SCCA competition.
