Whether you are upgrading your coil-over kit for track use or autocross, Eibach’s manufacturing excellence ensures that your vehicle remains planted and predictable through every corner.

Technical Specifications and Benefits

  • 400 lbs/in Rate: Ideal for stiffer suspension setups, providing improved body control and steering response.
