Product Details
The Swift Spec-R Lowering Springs for the 2022+ Toyota GR86 (ZN8) bring Toyota's lightweight rear-drive coupe even closer to the pavement for sharper handling and a more aggressive track-ready appearance. These ZN8 GR86 lowering springs deliver an approximate 1.0" front and 1.0" rear drop with spring rates of 3.9 Kg/mm front, optimized for the GR86's double-wishbone rear and MacPherson strut front suspension. Built in Japan from Swift's proprietary H5S.TW spring steel, these GR86 springs reduce body roll and unsprung mass for improved grip, faster transitions, and more predictable slide control for autocross, HPDE, and drifting applications.
