The Swift Spec-R Lowering Springs for the 2022+ Subaru BRZ (ZD8) optimize the second-gen BRZ”s already-excellent chassis balance with a lower ride height and improved spring rates. These ZD8 BRZ lowering springs provide an approximate 1.0″” front and 1.0″” rear drop with spring rates of 3.9 Kg/mm front, tuned specifically for the BRZ”s MacPherson strut front and multi-link rear suspension. Made in Japan from Swift”s proprietary material, these BRZ springs are a top choice among autocross and HPDE competitors, delivering reduced unsprung weight, faster transient response, and the predictable limit handling that makes the ZD8 platform a joy to push hard.
