Product Details
The Swift Spec-R Lowering Springs for the 2014-2020 BMW M4 (F82) give the F82 M4 the aggressive, track-ready stance that complements its twin-turbocharged S55 power. These F82 M4 lowering springs drop the ride height approximately 1.1" in front and 0.9" in the rear with spring rates of 5 Kg/mm front and 13 Kg/mm rear, optimized for the M4's adaptive suspension and performance braking system. Made in Japan from Swift's proprietary H5S.TW spring steel, these M4 springs reduce body roll and improve high-speed stability for faster lap times and more engaging canyon carving.
