Features & Product Details

Cusco is one of the pioneering companies based out of Japan that has invested countless hours of research, design, and engineering to develop quality suspension and performance products that will improve your driving experience. Some of the fasted cars around the world who compete in time attack, time trials, and other racing avenues will more than likely have a Cusco product on their car.

This product is the Cusco Diffuser Bracket. The 06-07 USDM STI models came factory with a rear diffuser to help channel the air beneath the vehicle to improve both aerodynamics and high-speed stability. It is a streamlined look that is functional that is more appealing with those with prior year models. The Cusco Diffuser Bracket will allow those with earlier models to install the factory diffuser. 

Hardware will be included to make this bracket ready for the installation.

Fits your Kouki GC/GM 2 years ago
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!

Simple install 5 years ago
Stickle
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.

    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.

  • Q: 07 2.5i  Mustardman7 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.
