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 and 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.

Spec R springs are wound with the same engineering as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!
