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 key features that makes these a 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 highly 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.

    Will these work with the Tein EDFC Active kit on a 2004 WRX?

    • A: These are EDFC compatible but would need a Motor extension kit as well. For help finding all the needed parts, please contact a customer service agent and they will be happy to help!

  • Q: Will these fit:  Just want a lowered ride 6 months ago


    2004 Subaru Impreza RS Sedan 4-Door 2.5L 2458CC H4 GAS SOHC Naturally Aspirated? 'Choose your car' says No, but there shouldn't be too much difference between 2004 WRX STI and a 2004 RS Sedan's suspension?

    • A: Tein only confirms the WRX's and STI's for fitment.

  • Q: Cold Weather?  Blue04Wagon 1 year ago


    I live in a colder environment where the temperature can drop to anywhere around -40 (celsius) in the winter. Will this cause any problems?

    • A: Any coilover can have premature wear on the damper seals if it is exposed to those temperatures for long periods of time.
