Chassis stiffness is an often an overlooked aspect of performance that can be easily improved with a simple bolt-on brace. However, not all braces and bars are created equal.

We run our 10th Generation Civics on the street and track all the time. It's obvious to us that the cars could benefit from increased chassis stiffness. We knew we had to find a way to REDEFINE the Front Strut Tower Brace (FSTB) for this awesome community.

Performance, aesthetics, and additional bracing improve driver feedback and define the 27WON FSTB for all 10th Gen Civics… Type R, SI, and Base models alike.

The unique dual tube design and one-piece construction comes together to create a high-performance strut tower brace that improves chassis stiffness AND looks great in your engine bay.

One-piece construction has superior strength over a 3-piece brace and the dual tube design keeps the profile slim in the engine bay while complimenting the natural body lines of the 10th Gen Civic.

Installation is a breeze for CTR and not much more difficult for other Civics. For all non-CTR applications we include a new battery ground cable for proper fitment.

Available in addition to the FSTB as an upgrade or for purchase later is our billet aluminum master cylinder brake brace. The 27WON brake brace is designed to bolt on directly to your performance strut tower bar and press against the brakes master cylinder. The purpose of this is to reduce the flex of your master cylinder on the firewall.

By adding the brake brace you will reduce the movement of your brake master cylinder which will result in a more solid pedal feel and more consistent feedback when on track or under hard braking. This upgrade is a must-have for anyone looking to push the car's on-track performance.

Available in two versions, we have a Brake Brace for your particular Honda Civic.

  • Select (sedan & coupes-only) to get the correct brace to attach to your 2016+ Honda Civic, SI and other 1.5T 4-door and 2-door models. will not fit NA 2.0L models
  • Select (hatchback-only) to get the brace for your Civic Type R and all 5-door hatchback models 2016+.

1 piece design sub headline banner

There are two common design approaches for strut tower braces in the industry today: Bolted End-plates and Fixed End-plates.

Bolted end-plate designs allow for the use of different materials for the cross bar and the end-plates and are much easier to design and manufacture. However, the design has a weak point. The bolted connection between the cross bar and end-plates compromises rigidity. In single bolt connections the rigidity (buckling strength) of the brace is compromised by a factor of 4!

Fixed end-plate designs feature single material construction. This results in a more complex manufacturing method but the result is a design that is 4 times stronger than a similar bolted end-plate design.

Utilizing a one-piece design with a goal for superior strength and slim profile, steel construction was the ideal choice. Thick-walled dual tubes are welded to the tower plates utilizing center cylinder construction to provide a robust chassis brace.

All of our bars are finished off in powder-coat for durability and a sleek look.

You know if its a 27WON upgrade then we need to offer it up in some 27WON style. You can acquire this bar in either a Wrinkle Black powdercoat or in our Signature Orange powdercoat. Which ever option you choose you will be adding some bonus style points under the hood.

Installing Your Performance Front Strut Tower Bar

Difficulty: 1/5

Some people say that FSTB doesn't do anything for this Civic but i would definitely disagree

The 27Won FSTB makes my turn ins much quicker and sharper, giving me more confidence and i think it saved me from an accident because in the 2 months after I installed it. I was accelerating to change lanes and the car in front came to a complete stop abruptly to give way to another car turning out. Without the 27Won FSTB, i may not have been able to swap lanes accurately and quickly enough to avoid side swiping the car in front

Power is nothing with control, and 27Won FSTB gives you the confidence and control for your Civic!
I am very satisfied, the bodywork is more solid when cornering.
its orange color is too pretty and attracts people's curiosity. 10/10
What can I say. Strut bar looks and feels great. Great craftsmanship feels good when I drive. Got the break master cylinder brace with it too. Make sure you tighten up the bolts good on it. I didn’t do it and was hearing a squeaky noise coming from engine bay I tightened them up and no more issues.
I highly recommend this from 27WON. Best part of it all is their customer service UNBELIEVABLE.

oh by the way just received my FMIC. Next will be big turbo.
Honestly I love this bar, i didn't know what to expect but i have the street RMM and the intake. i wanted to see what the difference was with the fstb and it feels great, handling has improved over stock. 10/10 recommend
Great product would highly recommend and 27won does it right you will not be disappointed
I paired this with BC coils with swift springs. Fantastic!
Amazing product, amazing customer experience, amazing company as always. 27won always provides the most amazing experience from ordering to unboxing..thanks guys and you have a life long fk8 customer owner here!
Best strut tower bar on the market for the Civic. Can feel the better handling when going down winding roads.
Extremely well crafted, great packaging and appreciate the hand written note. Next up is the fmic.
I’m actually surprised how much the steering has improved! I can really dive into corners now without feeling like I’m driving a waterbed… The front end of the car feels a lot stiffer and more responsive to quick steering inputs. Basically the car became a lot more fun to drive and I’m a lot more confident when taking turns.

NVH has increased slightly after installing the strut bar but that’s fine; i love it.

Also no need to say how good it looks in my engine bay…????

Brake pedal feel has also greatly improved after installing the brake brace. It feels a lot stiffer and more responsive than before.

One downside i did notice was the brake brace became a bit loose after using it for a while, but I’m sure that’s normal.

All I can add is I wish I bought this mod sooner!
