Product Details
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 H5S.TW 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.

- Increased spring rates tuned to usable shock stroke for balanced performance
- Fewer coils reduce unsprung mass and completely eliminate coil bind
- Quicker transient response for improved traction and road feedback
- Vehicle-specific bump rubber engineering to prevent bottoming out
Features
