Review & Installation Video

Review & Install Video

Hey, guys, Stephanie with americanmuscle.com here with an overview of the Steeda strut tower brace for the 2015 and up S550 GT and EcoBoost Mustang. In this video, we're gonna be talking about the materials and construction of this truck tower brace and a little about the install as well. This is an easy install. It's gonna be a one out of three wrenches on the difficulty meter, but I will go into more detail later about the install. This strut tower brace is the perfect option for the S550 owners that are looking to add the benefits of a strut tower brace but that want something different than the standard OE strut tower but they still wanna stick with the parallel beam design. A strut tower brace does have some handling benefits, but it also has an impact on the underhood styling as well. This brace looks different than any of the other options in the market right now. The thought process behind the strut tower brace is that it can tighten up some of the freedom that the front end has. Since a strut tower brace is gonna help stiffen the front suspension of the Mustang by providing added support to the strut towers and providing flex during cornering. This is gonna make the chassis more rigid, which will result in better handling, because eliminating the flex in the strut tower will work to maintain a flat tire on the ground at all times, giving you as full of a contact patch as possible. This brace is made from tubular Chromoly steel and this brace will work on all 2015 and up GT and EcoBoost Mustangs no matter the package or trim of the car. By that I mean it'll work with or without the stock performance package Cabriz [SP], but it does work best performance-wise with the help of that Cabriz just as any strut tower brace would. And, of course, it is powder-coated wrinkle black to keep the good looks. Keep in mind that like a lot of other suspension parts, a strut tower brace is gonna make a noticeable improvement by itself even on a completely stock car. But as usual, remember that this is only one component of the suspension and the improvements of the brace can be even more considerable when you start pairing it with other suspension mods. Once you start making other suspension upgrades, the strut tower brace will work to keep everything tied together and feeling tight and more stable. This means overall more consistent suspension no matter what you're doing with your car. As far as price, this brace isn't what I consider expensive, but it is one of the more expensive options. It's priced closer to the Mishimoto and Ford Racing black braces, so you can expect to pay around $200. One thing to keep in mind when you're shopping for strut tower braces is your future mods. So just be sure to shop around for a taller brace if you plan on things like superchargers or a taller manifold. If we move on to the install, this is an easy install that anyone is able to tackle by themselves in the driveway at their garage. Should take less than an hour to complete, and I'm gonna call it a one out of three wrenches on the scale. Won't need any tools out of the ordinary, just a 13-millimeter socket with a ratchet. The instructions are very easy here. The brace installs with only four bolts on each side. There are four nuts that are on each side of the strut mount. Just back the nuts off of the studs here and place the brace on the studs. You align the brace by centering the studs in the brace holes. You wanna loosely thread the nuts back onto the studs then, and once the brace is aligned you can fully tighten down the nuts and that's all it's gonna take. I'd take the car for a quick test drive and make sure everything feels okay, and then go from there. Wrapping things up here with the Steeda strut tower brace, this is a brace that has a parallel beam design and has a tubular Chromoly steel design that's powder-coated black. As always you can check it out more online right here at americanmuscle.com.

Reduce Flex And Improve Handling. Eliminate unwanted chassis flex and improve the handling of your S550 Mustang by installing a race-tested Steeda Strut Tower Brace. The parallel beam design of this Strut Tower Brace adds additional strength to make your Mustang handle like it is on rails.

Impressive Steeda Styling. The Steeda Strut Tower Brace is completed in a classic black wrinkle powder coat finish for long lasting durability, and features a polished billet "Steeda" emblem for impressive custom under hood styling.

Tubular Construction. Steeda designs and manufactures their Strut Tower Braces in the USA from tubular 4130 chromoly steel in a parallel beam design for superior strength to keep your front end from flexing under the monster torque of your Mustangs powerful motor.

Easy Bolt-on Installation. This Steeda Strut Tower Brace is a simple bolt-on upgrade that clears the factory intake manifold including the plastic engine cover and is easily installed with just basic hand tools.

Application. This Steeda Strut Tower Brace is designed to fit all the 2015 to 2017 GT and EcoBoost Mustangs equipped with the Non-Performance, Performance Pack and 20" Wheel Option packages. Does not fit 2015-2017 V6 Mustang models.

Will this strut tower brace work in applications where a Whipple Supercharger is installed. 2016 Mustang GT

  • Whipple Superchargers are rather tall and the clearance would be very minimal or non-existent with the Steeda Strut Tower Brace. Due to the myriad combinations of superchargers and strut tower braces, we have not been able the confirmed fitment of this combination, we apologize.

Can you still remove the intake manifold cover with the brace installed? With my 2011 5.0 I could not.

TKey

  • If you were to remove the intake manifold cover, I would suggest taking the brace back off because you will not have the proper amount of space to work with if you do not remove it.

    The difference is night and day. Noticeably tighter handling. My girlfriend noticed as soon as she sat in my car without even knowing I had installed it. Only gripe, and it's not really Steeda's fault, but they could remedy the problem: the two inner studs are a different thread pitch than the two outer studs. The provided nuts work great on the outer studs, but reusing the OEM outer nuts on the inner studs only works for two of the four requiring nuts.

    Added it to Ecoboost Performance Package

    Even though the Ecoboost Performance Package comews with the k-brace from the strut towers to the firewall, it is just not enough. After adding the Steeda tower brace my Mustang exhibited significant improves in handling and overall front-end stability. Bumpy roads have less detrimental effect on steering even. I got a much bigger improvement than I expected.

    The Better Brace

    I like this brace due to it's custom race look and that the chromoly will flex less then any of the other brace materials out there. I only wish there were more color choices

    Should Have Been Standard Equipment on GT

    This brace is probably not for the all-out racer but it noticeably improves handling and cornering. It was a breeze to install. I didn't disconnect the positive battery terminal as the directions called for, until I tried to squeeze the brace under it. Wouldn't go until I did it. The directions are easy to follow and all the fasteners and spacers are included. I put several coats of clear coat on the shiny aluminum name plate before attaching it to the brace. That job took almost as long as the entire installation.

    great mod

    Ordered this steeda strut tower brace and it shipped fast. After taking it out of the box I looked at all the hardware, I was unsure where some of the parts went but when you take a look under ur hood it's easy to see where the spacers and nuts that came with it go. Install took about 5 minutes. After the install I stood back and took a look and was impressed on how nice the quality is and how well it fits. When I went for a test drive I could feel the difference, the handling was much better. If you are looking for a mod that looks great, is a great fit, and is functional then I suggest this steeda strut tower brace.

    Flatter cornering only a couple hours away

    I installed this brace on my EcoBoost (w/ Performance Pack) in about 2 hours and was immediately impressed with the reduction of flex and improved body posture in the corners. The install is straightforward, however make sure you have a torque wrench on hand and I found that a pass-through head socket wrench makes loosening factory bolts a lot easier. The only knock on this brace is the Steeda logo plate, which looks out-of-place on the beautiful powder coat. I would have liked to have seen a flat finish on the plate or something a little more subdued.

    Stut brace 2016 gt

    The product was shipped very fast, was well packed and came with decent instructions. All the hardware was accounted for. The product itself is well constructed and allows easy access to the dip stick due to its tubular construction. In my opinion it looks better then the factory brace and can be purchased at a much lower price. Installation took about 15 minutes. You spend more time installing the name plate then actually bolting it to the car.

    steeds strut bar

    Fit perfect looks nice and great price only problem that I had was that none of the nuts for the 8 bolts were labeled in separate packaging so when I put two on with out knowing they were different sizes I broke the strut bolts loose from being pressed in so I had to weld them down to be able to get the nuts off and to put the right nuts on besides that I love it looks good and handles even better

    The Steeda strut tower brace looks great and was easy to install. I like the twin bars which make it easier to get to the oil dip stick. I had no problems with the bolts on the name plate as another reviewer stated. Maybe Steeda corrected the problem because my installation was a breeze. Great product as always from Steeda.

    Brace does it's job but it's not worth the hassle.

    The strut tower brace in and of it's self is good. Install of the brace too less than 30 min once I finally got to that part. The issue I had, and what took a 45 min install hours was the silver Steeda vanity plate was a pain to get on. First off the image shows bolts that use Alan keys, what I got in the box were cheap Phillip's head screws that looked like garbage when installed. The screws were also supposed to be held on with locknuts that couldn't be installed do to a combination of the bolts being too big to match up against the holes and the actual pipes of the strut bar preventing them from even getting to match up in the first place. In the end I had to go to a local hardware store and find pieces I needed that worked most of the way. I'm still planning on just taking the bolts I bought out and welding the plate on. So if you don't care about getting the look the product advertised, and all you want is performance, then the brace is pretty decent. But if you want to get what you paid for vanity-wise as well either don't get this or prepare for a minor head ache.

    Low cost for the return in performance

    I just installed this on my 2017 ecoboost mustang, and it made a very noticeable improvement. It takes bumps better, stays flatter when cornering, and just seems to make the car ride a little firmer. Also fits, and looks great!

    Rock solid, can't remove engine cover

    Super easy install, fits perfectly, includes replacement lock nuts rather than reusing the factory nuts with loctite. Clearance for the tiny nuts that hold the Steeda nameplate on is annoying, takes a special technique to get those going but not too bad. Also, clearance for the fastening bolt between the tubes was too small to run down with a socket, had to finish with an open ended wrench 1/4 turn at a time. Only complaint is you just barely can't remove the engine cover with this brace installed, only by 1 or 2 mm... why Steeda, why? It does have a noticeable effect on front end stiffness, especially hitting bumps mid-corner (proved out on Michigan roads). Also looks great under the hood and maintains access to the oil dipstick. Maybe a bit expensive... $200 for some steel tubing

    Review of Steeda Strut Tower Brace

    I recently purchased my first Mustang, a 2017 GT and also joined the local Mid-FL Mustang Club. In February the Club had a well attended annual Mustang show, which was my first car show. I decided right then to work toward showing my Stang. I looked at the available struts on the cars in the show, some had a Steeda and others had a solid flat brace. I feel that any brace is better than none, but the Steeda looked lean and stronger. I had my 5.0 engine covers and the Steeda painted the same color as my car, Ruby Red with a clear coat. Also, the American Muscle staff have been very helpful helping me select add on's for my car.
