    Good stuff! 1 year ago

    This was my second pair of coilovers for my 05 Impreza sti. And I was happy that I bought these. My old coilovers was more basic and not as near as god. Hks did a really good job making these coils both comfortable and good for handling. When cornering in high speed they handle it ass good as you want and they are really good adjusted right from the box! Would recommend these!!

    • Q: Fitment  SubiWRX0310 months ago

      Will these fit a 2003 wrx? I really want to run these coilovers but don't know why it says only for 2005-2007 because most say for 2002-2007 wrx/sti.

        A:  The 02-07 WRX and 2004 STI have a different hub design than the 05-07 STI, so the lower mounting brackets for coilovers are different. This would be the part for your vehicle:

    • Q: Suspension travel  ericclover465151 year ago

      Can you tell me how much suspension travel is allowed with these coilovers?
    • Q: Bottom Mounts.  Lark_thelandshark1 year ago

      I have the WRX set of these and am doing a full STI transmission and brake swap to the 5x114 hubs. Is there any way to get only the bottom part of the front coilovers?
