The Swift Spec-R Springs for Scion FRS & Subaru BRZ are designed at the upper limits of the OEM shock valving, and are track tested, tuned and tested again to provide optimal performance that's great for the track yet comfortable enough for a daily driver.
When Swift set out to make new, driver oriented springs, they had 3 main goals.
Spec-R springs are wound with H5S-TW, the same material used with the Swift Sport Springs. Even with the increased stiffer rates and slight change in ride height, you can expect the same great characteristics as the Swift Sport Springs.
Every Spec-R Spring that is offered by Swift has been carefully designed with your vehicle weight, stock struts and parts in mind, to achieve the most performance you vehicle is capable of, while still maintaining enough comfort for daily driving.
