Description

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.

On this page, you are viewing the Cusco Rear lower Subframe Bar. Cusco designed this bar out of tubular steel to help reduce weight over the stock bracing without compromising the strength. Additionally, this rear lower subframe bar will also improve the overall chassis rigidity of the vehicle. This bar will come ready to install, and it will come powder-coated in the flagship Cusco Blue for extra protection against corrosion. 

NOTE: May not work with aftermarket swaybar mounts.

rear lower subframe brace
Calvin 7 months ago
installed on stock 05 sti, stock horse power, stock rear sway bars. butt dyno says the rear end of the vehicle feels more planted with the sticky tires on, less body sway this thing is pretty simple to install. I recommend that you remove the rear sway bar entirely, unbolt the evap canister (has 3 10mm nuts holding it) and remove what ever lines are in your way, then unbolt the stock sway bar mount and install the passenger side section first with this brace on the frame, then the sway bar bracket, then screw in the driver side sway bar mount. the passenger side kinda sucks too do by your self so get a friend if possible. AT first the stock bolts seem too short, but I gave it the german spec torque value and it checks out ok, nothing broke yet hitting turns or launching the car, feel free to buy a longer bolt if you feel uncomfortable

This is a must if you want oem sti diffuser along side with the two brackets. Also stiffens the rear end a bit more. Overall perfect material

04 FXT Cusco subframe brace
04Scooby 2 years ago
I have a 04 forester xt. I bought the cusco rear subframe bar for it and it fits perfectly. It was a little bit of a pain getting the bolts in on the passenger side due to the charcoal canister, but if you remove it, it'll make it easier for you. Did a great job stiffening up the rear. Also have the whiteline front sway bar and whiteline sway bar bushings and end links. Definitely recommend

Love it!

Made a substantial difference. I was actually shocked by it. I now need a bigger front sway to help count what this and the whiteline rear sway bar did together. lol Would definitely recommend this part! My car is now more tail happy then ever... whoops :D

  • Q: 02 wrx with 25mm perrin sway bar, stout mounts +exhaust  CodyBear6 9 months ago

    Answer

    I have an 02 wrx with a perrin 25mm rear sway bar, perrin stout mounts, and a perrin 3" catback exhaust, will the rear diffuser set up work? Thanks


    • A: It shouldn't have any issues, though Perrin won't confirm it nor will Cusco as they haven't been tested together.

  • Q: Fitment of CUSCO Rear Lower Subframe Bar on 2004 STi  RJN119 1 year ago

    Answer

    The aforementioned STi has a Cobb Exhaust system as well as Cobb Sway bar and end links. Will the CUSCO part fit? Thanks


    • A: We have not test fitted these parts together so we are not able to confirm fitment.

  • Q: Fitment with aftermarket swaybar  02bugeye 2 years ago

    Answer

    (2002 wrx sedan.) -Wondering if this brace will fit with a eibach 22mm rear sway bar using factory sway bar brackets?


    • A: If you are using the factory sway bar mounts, there shouldn't be an issue with this bar.

  • Q: Extra parts?  SpennyDerp 2 years ago

    Answer

    I have the 2002 WRX Wagon and was wondering, do I need other parts to install this part? New Brackets? Bolts and such? If so what do I need?


    • A: This reuses OEM hardware and will bolt directly on the vehicle, although many customers use this part to also install the STI rear diffuser which we sell brackets and hardware for.

  • Q: Fitment with Whiteline rear sway bars mounts  Drowland87 3 years ago

    Answer

    I'm interested in installing the rear diffuser on my 05 STI. Will there be any issues installing this Cusco Rear Lower Subframe Bar with my Whiteline Forged Aluminum Sway Bar Mounts 24mm Part #: WHI KBR21-24 ?


    • A: We have had fitment issues reported with this bar and the Whiteline sway bar mounts. They will not fit together unless you trim part of this bar, and you can see the compatibility issue in the User Media pictures.
