The Swift Sport Springs For Your Lexus 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.
