Product Details

The Swift Spec-R Lowering Springs for the 2022+ Lexus IS500 (USE30) give the IS500's naturally aspirated 5.0L V8 the chassis support it deserves with a lowered center of gravity and optimized suspension geometry. These IS500 lowering springs deliver an approximate 1.0" front and 0.6" rear drop with spring rates of 6.5 Kg/mm front, designed to work with the IS500's Adaptive Variable Suspension system. Built in Japan from Swift's proprietary H5S.TW spring steel, these IS500 springs reduce body roll and improve corner-exit traction, letting you make the most of the V8's power on both track and street.

Swift Spec-R Technology

  • Proprietary H5S.TW high-tensile spring steel, manufactured in Japan
  • Optimized ride height to maximize suspension geometry at lowered position
  • Increased spring rates tuned to usable shock stroke for balanced performance
  • Fewer coils reduce unsprung mass and completely eliminate coil bind
  • Quicker transient response for improved traction and road feedback
  • Vehicle-specific bump rubber engineering to prevent bottoming out

Features

  • Track-proven in HPDE and SCCA competition
  • Lowered center of gravity for improved cornering grip
  • Reduced body roll and sharper handling response
  • Comfortable enough for daily driving
  • Compatible with OEM and aftermarket shocks/struts
  • Direct bolt-on installation with no modifications required

    Great!

    Loved the amount the car dropped (not too much), feels OEM, easy to install, happy with the springs and the service from Springrates.

    Perfect ride!

    After adding a new set of tires and wheels with a bigger offset to push the wheels out I needed a set of lowering springs to set them off and you had just what I needed. Got the installed and an alignment done and now every time I get in the car it feels like a new car to me. Improved not only the looks and handling, but also the ride. Firm, but not harsh and the electronic damping system on my 2023 Acura TLX Type S still works perfectly. Highly recommend!
