Product Details

The Swift Spec-R Lowering Springs for the 2007-2013 BMW 335i (E90/E92) transform the E90 sedan and E92 coupe into sharper, more composed driving machines with a lowered stance that matches the 335i's performance potential. These E90/E92 335i lowering springs provide an approximate 1.0" front and 0.8" rear drop with spring rates of 4 Kg/mm front and 11 Kg/mm rear, designed to work at the upper limits of the stock shock valving. Built in Japan from Swift's proprietary H5S.TW material, these 335i springs are popular with HPDE and autocross enthusiasts who want reduced body roll and improved weight transfer without a harsh daily ride.

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!
