A performance Front Strut Tower Bar (FSTB) is a very popular first modification due to its relatively low cost, ease of install, pleasing aesthetics, and improved driver feel.

The 27WON Strut Tower Brace for the entire CivicXI generation and 5th Gen 2023+ Integra combines all the features above into a bar that truly does REDEFINE the Aftermarket.

Check out the rest of the listing below for all the details on why this is the only bar you want to consider for under your hood.

redefine design graphic

We created the 11th gen Civic and 5th Gen Integra FSTB by starting with the best 10th gen Civic FSTB on the market. A twin tube design with 4x weld contact points means a bar that truly puts in work by reducing any unwanted chassis flex.

Being welded at both ends rather than bolted on means you get a brace that actually does something and is not just some piece of aluminum bar stock with a badge under the hood.

Installation of the 27WON Strut Bar for the 2022+ Civic EX, Touring, Si or A-Spec 2023+ Integra can be completed in less than 10 minutes. 6x nuts off and 6x nuts back on is all that it takes to start enjoying your first performance mod from 27WON for the FE1, DE4 and even FL5 chassis.

A popular add-on for this strut tower bar is a sweet master cylinder brake brace. The brake brace attaches to your bar and anchors between the bar itself and the front of the master cylinder. This reduces movement of the master cylinder itself and improve brake pedal feel both off and on track.

Be sure to check out our blog here and see what the brace does and why you want it.

endplate graphic

Bolted endplate versus fixed endplate and why the choice matters for performance.

Bolted end-plate designs are much more common and cheaper to manufacture than fixed endplates. They allow different materials to be used for the main cross-section and endplates help control cost and makes them easier to make. Also, a generic piece of bar stock can be used to fit between the end-plates on many different vehicles by simply cutting to length. While this is a great way for the manufacturer to control cost, bolted connections are a weak point. In this application, the (buckling strength) of the brace can be reduced by a factor of 4!

Fixed end-plate designs utilize a single material for the cross bar and endplates that are welded to each other. This results more complex manufacturing but the result is a design that is 4 times stronger than a bolted endplate design.

twin tube subheadline graphic

Our one-piece design is created using two steel tubes for strength and a low profile under the hood of your car. By utilizing a strong yet simple design we leave room behind the bar for future add-ons like oil catch can's and flex-fuel sensors that are sure to be available for the 2022+ Honda Civic soon.

Open end-plates allow easy access to camber adjustments for aftermarket coilovers. We thought of everything to make this the first and best Front Strut Tower Bar for the FE1.

choose black or orange color graphic

You know if its a 27WON upgrade then we need to offer it up with some 27WON style. You can get 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

1/5 Difficulty


Fits, looks, great. Easy to install and adjust the brake brace. Had to cut/modify the Honda engine cover that I installed but made it work to be able to retain it.
Super easy install, the brace was a little finicky, but once I figured it out, dropped right in. Brakes feel way better and the chassis feels a lot stiffer now too. Really does make the front end feels more planted in the turns. Definitely be coming back for more!!!
It looks great. Just wish I knew what the torque spec was for the sport hatchback
The FSTB fit perfectly and looks amazing. I also ordered the master cylinder brake brace and was honestly surprised in the difference it makes as far as brake pedal feels! 27WON knocked it out of the park once again!!
