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 particular component is the Cusco Type OS Rear Strut Tower Bar. The intended purpose of this bar is to reduce strut tower flex by linking the two strut towers together. The benefit is reducing chassis flex under hard cornering for improved handling and improved driver feedback. A simple upgrade for those of you who enjoy high-performance driving conditions such as auto-x or a spirited canyon run.

This strut brace features durable aluminum construction with a polished bar, and the end plates will come in Cusco's flagship blue color.

rear strut bar 05 sti 11 months ago
Calvin
installed this on my stock 05 sti. was real simple to do, removed rear seat bench and backrest. only difference i can tell you is my "butt dyno" says that there is less chassis roll/body sway when maneuvering at freeway speeds and preloading chassis weight before turns

QUESTIONS & ANSWERS

  • Q: Modification necessary?  fourlowe28 days ago

    Is modification to the interior trim necessary in order to install this rear bar? Modification as in cutting or having to notch the trim to get it to fit or does it just arch over the trim?
  • Q: Fit with X Brace?  guest563299c24da8c365718b45d73 years ago

    Just installed the cusco rear x brace, will this fit as well?
    • 0 of 0 people found the following answer helpful

      A:  This strut bar is not compatible with the cross bar because they are for different vehicles, and the cross bar cannot be used with a strut bar.

  • Q: Triangle bar type OS  Zankazuya5 years ago

    on your Triangle Bar Type OS says it needs this part and is confirmed that the triangle fits the 1999 impreza 2.5 rs but the rear type strut bar doesnt so that kind of doesnt make sense can you clarify that this fits or doesnt?
    • 0 of 0 people found the following answer helpful

      A:  The correct Cusco rear strut bar for a 1999 2.5 RS is part number CUS 660 541 A and it is compatible with the Cusco triangle bar.

  • Q: spec-c 12l rear intercooler water tank  RTSC6 years ago

    will it fit with the above? doesn't look like it would
    • 0 of 0 people found the following answer helpful

      A:  With just the bar it should be able to fit but it will be a very close fit if it does. From images we have seen, most rear strut bars will fit with the tank
