Swift developed the Spec-R springs for the track enthusiast that wants to take their FT86 to the next level. The Swift Spec-R springs were engineered with 2 main goals.
1) Lower the ride height to optimize performance.
2) Increase spring rate to reduce body roll and increase cornering speed.
The increase in spring rate of the Spec-R springs is based on the factory shock valving profile and compatible with all factory shocks. Swift has carefully increased the spring rate to the maximum that the stock shocks can handle. Higher performance shocks are not required, but recommended. The Swift Spec-R springs pair excellent with our Koni shocks.
Sean's Application Notes: Unlike other lowering springs, the Swift Spec-R will improve your car's performance without breaking the bank. While these work adequately on factory shocks I'd recommend pairing with our Koni Yellows for a suspension combination that will outperform most inexpensive coilovers!
