Tein Street Advance Z Coilovers - 2002-2007 WRX / 2004 STI

If you're looking for a cost-effective coil over that will improve handling and ride quality without breaking the bank, then have a gander at the Tein Advance Z coil overs. 

These coil overs have several features that attribute to a great set of cost effective upgrade. These have sealed bodies that are height adjustable by moving the spring seat either up or down, and the Advance Z coil overs provide a smooth ride due to the Twin-Tube System. Tein designed their twin tube system to allow the suspension to negotiate and absorb gaps, bumps, and rough roads along with providing stability at higher speeds. Additional features include dust boots that will protect the piston rods of the struts from foreign materials and debris. No-Sag Springs will come with the coil over kit, and are fabricated from SAE9254 steel, and have a high durable powder-coating that will not flake over time. 

The bodies of the Advance Z coilovers feature Tein's flagship green powder-coated finish, and the threads located on the bodies have Tein's unique ZT coating surface treatment for protection against road debris such as gravel and dirt. The Advance Z coil overs will utilize your factory OE mounts, and they will come with an adjuster tool for users to make the desired adjustments.
