rear lower subframe brace 1 year ago
Calvin
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 3 years ago
04Scooby
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! 4 years ago

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

QUESTIONS & ANSWERS

  • Q: fitment and clearance  Nelson Asay8 months ago

    I am running the whiteline 22mm rear sway bar. I love it! Will there be any clearance or fitment in issues with this? Thanks RSD!
    • 0 of 1 people found the following answer helpful

      A:  There should not be any issues, however, there is little to no confirmation as they have not yet been tested for fitment together.

    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: Extra parts?  SpennyDerp3 years ago

    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?
    • 0 of 1 people found the following answer helpful

      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.
