Construction & Design:

The Ground Control Coilover kit features springs crafted by Eibach, a renowned name in suspension technology, ensuring precise spring rates tailored to the Scion tC’s chassis dynamics. The adjustable spring seats are constructed from premium 6061-T6 aluminum, anodized to resist wear and corrosion while providing a sleek finish. The square-cut threading on the adjusters locks the spring seat firmly in place, maintaining your chosen ride height even under aggressive driving conditions.

Urethane upper spring perches isolate the springs from the chassis, reducing noise and vibration for a more refined driving experience. Every component is manufactured or sourced from trusted American suppliers, reflecting a commitment to quality and reliability that supports the lifetime warranty.

Installation & Fitment:

This coilover kit is designed for direct fitment on 2005–2010 Scion tC models equipped with stock, Sachs, or Boge shocks. Installation requires lifting the vehicle corners to adjust the spring seats to the desired height, which can be done with the included wrench if necessary. Because the kit does not fully return to stock ride height, it is best suited for users looking to lower their vehicle for improved handling and aesthetics.

Installation is straightforward for experienced enthusiasts or professional shops, with no major modifications required. Always specify your shock type when ordering to ensure compatibility.

What's Included:
