So when you look under the hood of this 2013 Steeda Mustang, what most people think the biggest bang for the buck is going to be the Vortech supercharger. But in fact, it's the Steeda Double Bar Strut Tower Brace. Scott Boda here with Steeda Autosports to talk to you about, Strut Tower Braces. Now, what's a Strut Tower brace? Well, it's a brace that actually ties in the two strut towers. Now, Steeda has been making Strut Tower braces since 1988 with the Fox body Mustang. Now, back then, it was always a triangular three point strut tower brace, attached the strut towers and the rear firewall. Now, with the springs located underneath the strut towers, all the force of the suspension is pressing up. In fact, with the fox body, as you can see up to a quarter inch of deflection in hard cornering with the strut towers. By tying them together, it reduces that deflection, allows your car to handle better, rides smoother, and actually cuts down a lot on the noise, vibration and harshness that you see. Now when the S197s came out in 2005 when we switched to a double bar design. That's because unlike the 79-04 Mustangs, this isn't the actual firewall. It's a couple inches behind. So tying anything into it wasn't really doing anything in our testing. So with a double bar design, we used domestic DOM seven eighths tubing. Right. It's going to tie in both strut towers. We've got some gussets along the way. The nice Steeda Billet center plate. And like I said, what that's doing is we are spring and strut assembly underneath these strut towers. When you go in the corners and they want to start flexing, it really ties it all in together. So when we popped the hood, a lot of you might have thought the best bang for the buck was a supercharger. But let's face it, not all of us can afford a supercharger, even though we love the horsepower. It was actually the strut tower brace for less than $200 and a five, ten minute install. It really transforms the handling in your Ford vehicle. We say Ford vehicle. We mean it. We make them for the Mustang, the Explorer, the Bronco, Maverick, Fusion, Escape, Focus. You name it, we make a strut tower brace for your Ford vehicle. So if you like what you saw, hit like, subscribe, follow us on TikTok, Instagram, Facebook, YouTube.

Great quality part, fit and finish is excellent, really tightens up the front of the car. I purchased basically the full catalog of suspension for my 2008 Mustang GT all of which transformed the car and really taught it some manners. This piece is like the icing on the cake because unlike many of the other parts you see this one every time you open your hood.

My First Step
Anybody looking to buy from Steeda, do it. It's worth it. I ordered a Strut Brace for my 2014 Mustang V6 and it was my first step towards many other Steeda purchases. The shipping was a week longer than normal, but that was due to COVID, so I don't blame them. The product came in good packaging with no damage. The product itself is great material and doesn't feel cheap. There are plenty of videos on YouTube on how to install this piece. It was very simple. The Steeda logo on top comes separate but I would add it because it looks better with than without. My next purchase will be a Steeda Air Intake. I plan to utilize as much products from here as possible. I love their work. The piece I purchased was: 555 5718 Steeda Mustang V6/GT/BOSS 302 Double Bar Strut Tower Brace (2005-2014)

Steeda strut bar
This is a great upgrade for my mustang. Had the original OEM Ford strut bar on it and this Steeda version is stronger , lighter and looks way cooler. I just about switched all my suspension system to Steeda and this was just another piece to the puzzle. Quality built and can’t go wrong with Steeda parts for sure.

Good Upgrade
Brought this to help with body roll in the curves and it did not disappoint. I was able to notice right away an improvement in steering response and body roll immediate. Only took 10 minutes to install and would recommend to any 2005-2009 Mustang owner. Steeda delivery was quick and will defiantly be buying more parts form them.

All the help I can get
When driving a V6 in a crowd of Shelbys, GTs and the occasional Bullitt and Boss 302, you have to pretty much rely on handling to keep up. This brace is kind of the icing on the cake. Not only does it help stiffen up the front end, it lets people know that you're serious about your Mustang. Not everyone is going to crawl under your car to see what mods you've done. This brace will be the first thing that people notice when they open your hood. The Steeda name will say it all.

Looks Awesome
I bought this when I swap the stock intake manifold for the Boss manifold on my 2011 GT. Quality part, and it looks awesome. If you can hold a wrench then you can install this.
