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 Front 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. Hardware will be included to make this strut bar ready for the installation.

Cusco Front Strut Tower Bar Type OS ( Part Number: 6A1 540 A)
Removed an Annoying Dash Rattle 1 year ago
A pretty standard strut tower bar, but this one happened to eliminate an annoying 4000 RPM dash rattle that had existed since buying the car new two years ago. For that alone I'd say it was worth it. As for improvements to the handling, I can't really tell if it's made much of a difference. I did pair it with the Cusco rear strut tower bar as well - and had aftermarket front and rear sway bars on the car before this install.

New Zealand new 2015 WRX  2 years ago
I was concerned that this strut brace would fit my car as they can differ in little ways between countries,but I shouldn't have.It fits perfect and looks great and I can definitely feel the difference!

Starting my suspension build 3 years ago
This took me longer than any direct bolt on should to install. What should have taken 5 minutes took almost 20-30 min due too a poorly drilled passenger side, it didn't line up very well and was a struggle to get on but once it was on I went out for a drive and could notice very very slight better feel but I do drive a ton so I think it was easier for me to pick up on, I'm sure with more parts working together this piece will really tie it all together plus it makes the engine bay look nice. Worth the money for the most part

Awesome addition 3 years ago
I installed this strut bar in about 15 minutes. It made a HUGE difference in the handling of my car. Eliminated a ton of the understeer issues and made the handling more crisp.

      A:  There is the possibility this will fit with the Perrin Air Oil Separator, but unfortunately we have not test fitted that combination and cannot guarantee the fitment at this time.

  • Q: fitment  moe sabra3 years ago

    I want to order this strut bar as well as the Crawford AOS for my 2015 STI. Will I face any issues with fitment? Thanks,
    • 0 of 0 people found the following answer helpful

      A:  The Crawford AOS would likely fit with this strut bar on 2015 models, however we cannot guarantee compatibility because we have not tested them together.
