  • Q: Fitment  Charlie 4 months ago


    Hello, will these fit a 2002 model Subaru Impreza WRX STI?

  • Q: EDFC Active Compatible?  Alex M. 8 months ago


    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 8 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.
