SWIFT made Sport Springs Spec-R is made for true track racing enthusiasts that wants to take their vehicle to the next level.
Sport Springs Spec-R is engineered with 2 main characteristics.
1) Redesign lowering ride height to maximize the suspension performance
allowing the vehicle to fully absorb road condition for maximum
traction.
2) Increase in spring rate to further enhance cornering speed through
entry & exit. The increase in spring rate is based on the vehicle
factory stock valving settings. Sport Springs Spec-R is increase to the
optimal rate that the stock shocks can handle. Higher performance
shocks are not required, but recommended.
The Spec R springs are wound with the same engineering as their sports
springs. With the exception of stiffer rates and slight change in ride
height; you can expect the same characteristics as their sports springs.
