The Swift
Sport Springs For Your Infiniti are meant to keep the quality ride you get when your car
is new, but adds improved handling and a lower ride height for all
driving enthusiasts and style minded drivers seeking the best
performance out of their car.
When Swift
set out to make new, driver oriented springs, they had 3 main goals.
-
Maintain
or improve the ride of the vehicle
-
Increase
handling and reducing body roll and squat for perfect suspension
balance
-
Lower
the vehicle for looks, while keeping the shock within its usable
stroke
Many car
enthusiasts have had lowering springs installed on their cars before,
and many of them had bad results; harsh/rough driving, clunks from their
struts or they end up with a lowered car that handles worse than
it did at stock height with stock springs. To solve this, Swift
has created a proprietary material to make their springs out of-H5S.TW.
H5S.TW ha a much quicker transient respond, and will react to any road
conditions which provide a smoother ride on harsh road surfaces when a
normal spring will cause the tire to bounce and skip these road
imperfections.
Every Sport
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 keeping a comfortable
ride.
