CA Residents: Cancer and Reproductive Harm WARNING

Hi everybody Brian from here today to speak to you about our G-Trac Braces for the front of your S550 Mustang. Like many auto manufacturers, Ford assembles the current Mustang in pieces. They put the rear subframe together and its components and then the front subframe together and its components and obviously assemble the car. Now when we're putting the front subframe together the subframe itself actually is pretty wide at the rear mounting points and the reason they did this is that it could accommodate multiple engines, of course the Coyote 5 liter the EcoBoost as well as the v6 in the earlier S550,models but those bolts being so far apart allow the body to kind of flex and kind of roll. We have two solutions for this that will tie that in and the benefits to this are sharper handling, better chassis feedback and more effective use of even the factory suspension or any aftermarket suspension you throughout the car. Let's begin with our Ultralight Two-Point G-Trac Brace. Now again this connects the two outermost points. We construct this of chromoly tubular steel in particular to rectangular and the reason we do this is because we want to use a lightweight material but we also want to have enough surface area to really stiffen up the front of the car, again to improve handling and chassis responsiveness. For you GT 350 owners this is the right application for you and for some of our GT owners that have long tube headers this may also be the right choice for you. If you have questions about fitment please reach out to us. Now for you corner carver's out there, we offer an Extreme G-Trac Brace this mounts in four points and triangulates those four points just like our Ultralight G-Trac Brace our Xtreme G-Trac Brace is made of chromoly tubular steel now we went to a tubular steel because we have four points to distribute the load this also means that even though there's more material it's lighter weight 15% lighter than the competition. Both of our braces come with all the hardware required for installation and they don't require any modifications to the car. Furthermore we realize that the subframe is actually a stamped tubular steel and that when you tighten the bolt and a nut against it can actually crush down so we've also provided inserts to prevent that from happening. Again taking things one step further than our competition to ensure that you have a great handling car. Furthermore these are powder-coated for durability and we back them with our Steeda lifetime warranty. They're manufactured in the USA at our Valdosta Georgia manufacturing facility because Speed Matters. So which one is right for you the Ultralight Two-Point or the Extreme Four-Point G-Trac Brace. if you have any questions or comments about this video please feel free to post them below.

G Track Bar
Had the G Track bar installed on my 2020 GT-350 and the trans lining issue isn't as bad after the G Track installed however turning corners is amazing.

Exceeded Expectations
I was pleasantly surprised by the improvement in tramlining, but I was more surprised by the noticeable improvement in turn in and steering response on my 350R. Installation was a breeze and it made something that was already great even better.

G Track Bar
I have noticed some improvement after installation concerning tramlining. I would suggest better fasteners for example nyloc nuts in lieu of what was sent for easier removal if needed.

G-Trac Brace for Bullitt
Added this to a 2019 Bullitt with Magneride. My goal was to improve handling without adversely affecting ride or ground clearance. After installation, I immediately felt the difference regardless of steering mode setting. Steering felt more connected and responsive without adding harshness. Exactly what I was looking for!

G-Brac for GT-350
Just installed the brace! Installation was as easy as the video shows. The brace and all hardware are top quality. I highly recommend using the 22mm wrench and socket (1/2 " drive) as it will make the installation a breeze. I have not got to drive the car much with the brace installed so I can't provide as to how much the tramlining has been reduced.

Amazing stability
I was astounded at how much of a difference this made on the front of my PP GT. Really tightened up the front end and delivered considerable feeling.

Great fitment design.
Brace bolted up nicely with my rhino ramps up front. Used spacers to avoid any rubbing issues. Love Steedas engineering.

After installing the 2 point G Trac brace on my 2019 Mustang GT convertible (with the PP1 package), the straight line stability was greatly improved. I also noticed a more stable turn in on challenging curves at high speed. I consider this brace to one of the best mod's one can add to their Mustang.

Tame the Tramming
Took longer to jack the car than the installation. I bought this as other reviewers who own GT350's said it helped with the tram lining. I can 100% say yes it has. The tram lining is still slightly there, but a great improvement.

Great quality
2019 GT/CS Convertible with 10 speed auto. I was nervous about the fit due to the auto trans. The bar was touching the auto lines when I did a test fit. Fortunately steeda includes some spacers which I used. There is about a gap between the bar and the trans lines now. Installed using some floor jacks . Took about an hour total. Great quality, easy install even without a lift which probably would've cut the time I'm half. Ride feels better, less float in the front. Might upgrade later to the k brace but overall I'm happy with this for weekend cruising.

Easy install
The install is easy with the hardest part getting the slugs out of the mustang frame.It does improve the tramlining a great deal but in my case, GT350, there is still a bit left. The steering feels more solid as well. I was able to install the brace without jacking up the car by backing it half way out of the driveway.

the bottom end feels stiff now
I want to thank David at Steeda, and everyone there at Steeda for what they do for us guys and gals for our Mustangs. I just Installed on my GT350 the new Steeda S550 Mustang Ultralite 2-Point G-Trac Brace, it helped the lower end of this 350 a lot, it helped take the little bit of steering wondering from side to side, and made the bottom end feels stiff now and that side to side wondering is now gone.... The Steeda part is a must for this new GT350 the best $79.95 I have spent on this car Beside the Steeda 35# Clutch spring. thanks John
