Product Description

The TEIN GSB14-8UAS2 Street Basis Z Coilovers are designed to give your 2006-2011 Honda Civic 4-door sedan a lowered stance, improved handling, and a sportier driving feel without sacrificing daily comfort. Built using a steel twin-tube damper design, these coilovers balance ride quality and performance for both city driving and spirited weekend runs.

With ride height adjustability via threaded shock bodies, you can lower your Civic by up to approximately 3 inches in the front and nearly 2 inches in the rear. TEIN's cold-formed springs maintain consistent performance over time, while the Z-Coating on the threaded sections provides excellent corrosion resistance for year-round use.

This kit ships unassembled, requiring the springs to be mounted onto the dampers before installation. The design reuses OEM top mounts, making the system a direct bolt-on upgrade without permanent chassis modifications. Backed by TEIN's 1-year limited warranty, the Street Basis Z kit offers long-lasting performance and reliability at an affordable price point.
