    Fits your Kouki GC/GM 6 years ago
    5out of 5stars
    dlora.co22911
    This DOES indeed fit the GC/GM model as shown in their installation guide: http://www.cuscousainc.com/downloads/dl/file/id/114/672_487_s_aerodynamic_body_parts_rear_diffuser_bracket_subaru_impreza_wagon_gc8_applied_d_gdb_applied_a_e_gga_ggb.pdf Unsure if the GF would also apply. So long as you have the Cusco rear lower subframe bar 673 487 A to go with it, you can mount these two Cusco pieces, and connect the '05 STi diffuser and have that on your GC! Like mine :) A quality piece!

    As stated below. Will need two bolts and two locking nuts for the rear bar attached near bumper area. As they are not included with the support bars. Also a 4mm allen head key is needed for the four front screws.

      Will it bolt to a cobb strut bar?

    • Q: Hardware required?  Subenoob42010 years ago

      Does this come with required hardware (fasteners) or do I use existing hardware already on the vehicle? If required hardware is not included, what do I require? Thanks.
      • 0 of 1 people found the following answer helpful

        A:  To install the diffuser you still need the following 1x CUS 673 487 A 4x SUB 901000365 Along with the diffuser itself.

    • Q: 04 wrx fitament   ctom2411 years ago

      What would I need to get this to fit on my 04 wrx?
      • 2 of 2 people found the following answer helpful

        A:  You would also want to get the Cusco rear lower sub frame bar, the STi diffuser, the STi diffuser bolts, and this product itself, and it will all bolt up just like stock to give you the OEM diffuser. Thanks.

    • Q: 07 2.5i  Mustardman11 years ago

      Is this all I need to mount the STi JDM rear diffuser on to my 07 2.5i? And will this work with any aftermarket diffusers as well?
      • 0 of 1 people found the following answer helpful

        A:  Hello, You will also need the Cusco rear lower subframe bar, the STi JDM diffuser, and the STi diffuser bolts as well. And I am not sure if this setup will work with the aftermarket diffuser, but it is guaranteed to work with the OEM diffuser on the WRX and STi.
