      Review & Installation Video

      Hey, guys. Stephanie with here with an overview of this front subframe chassis brace from BMR for the 2015 and newer GT and EcoBoost Mustangs. In this video we're gonna discuss what this brace does and how it's designed to work, and the materials in construction, and of course, the install as well. I'll go into more detail later, but the install for this brace is easy. It's 100% bolt-on item that you can install with simple hand tools.The BMR front subframe chassis brace is going to be something that you should check out if you're looking for a way to increase steering stability and give the K-member some more bracing. This brace ties together a few points in the front of the car to support and stiffen the front of the suspension, and it's gonna be for street performance, drag racing, and any handling applications.So, first things first, this brace is made from a combination of heavy duty two-and-a-quarter-inch steel and one by one-and-a-half inch rectangular tubing. It ties in the front lower control arm mounts to the rear legs of the K-member. These areas are important to support because the factory K-member and the lower control arm mount can deflect, and this deflection is what's gonna take away handling performance.The design of this brace, by tying the lower control arm mount and the rear legs of the K-member, reinforces the major areas of the K-member to reduce that deflection. Reducing deflection here means a better steering feel and more stability, whether you're taking corners or even under hard braking. And the good news about a brace like this one here is that you tie in these points on the chassis, you reduce deflection, and you get better handling results, but you aren't gonna increase NVH or noise, vibration, and harshness.A lot of times when you go to reduce deflection, you end up taking the road of swapping out soft rubber bushings for more firm bushings or maybe even no bushings at all. But those methods add NVH. A brace like this one here avoids adding NVH but still gets you the results that you want. This brace also has CNC machine that build an aluminum spacers for you and it's gonna come with your install hardware, too.Like I said before, it's 100% bolt-on, so it's gonna use existing bolt holes. Now, adding a brace to the K-member like this is going to open up some questions about fitment, and of course, a long tube headers are gonna be a concern. This brace will work with the stock and very nearly all aftermarket exhaust systems, including most long tube headers. It will not work with Kooks long tube headers though, so just keep that in mind. It's also not gonna work on V6 models. And lastly, probably not your main concern here today, but this brace is available in both black and red powder coated finish.When it comes to price, you're gonna expect to pay between $100 and $200 but closer to $100 for this brace. Now, I don't really have anything else to compare this brace to since BMR is currently the only ones out there making a brace like this for the front of the S550. I will say though that for close to $100, I'm not sure how you can go wrong here if you're looking to stabilize the front end. Good materials, great construction, the benefit of BMR's proven reputation and the science behind the product are all positive here.Moving on to the install, like I said earlier, this is a direct fit item, so the install is gonna be straightforward and simple. You're looking at an hour tops in the garage and a one out of three wrenches on the difficulty meter. The job can be done on jack stands if you don't have access to a lift, but as always, a lift would make things easier for you here. Your wheels need to come off and you're gonna need to pull the lower control arm bolts. The spacers will go into the subframe and to the mounting hole, and then you can fit up your brace and reinstall the lower control arm bolts.One thing I will say here is that aligning the bolt holes might require some help from another person. If you have trouble, a second person can pull out on the hub and rotor assembly so you can line the bolts up and get it through. Your remaining bolts are gonna go into the rear mounting holes with the supplied washers and lock nuts. BMR suggests tightening the front bolts first and then the rear bolts, and they give the required torque rating in the step-by-step install instructions that do have pictures as well to help you guys out. Overall, it's a very easy install for anyone.Wrapping things up with the BMR front subframe suspension brace. This is a brace that's gonna tie together the rear of the K-member and the lower control arm mounting point to provide for some front end stability and less deflection without any added NVH. This is a good mod for any performance vehicle and it provides more stable handling performance all the way around. As always, I suggest you check it out more online for yourselves right here at

      Track-Ready Stability. BMR offers great help for the handling of your 2015-2020 Mustang. The front K-member on the Mustang is quite strong straight from the factory, but still tends to flex under extreme use. The BMR Front Sub Frame Chassis Brace increases steering stability and reduces the need to make repeated front alignment changes on your S550 Mustang. Thanks to heavy-duty steel construction and smart engineering, it does this without increasing noise, vibration, or harshness (NVH) in the cabin.

      Reduces Deflection. The BMR Sub Frame Chassis Brace ties the front lower control arms to the rear legs of the K-member, adding stiffness to the whole structure. Deflection under cornering and braking loads is considerably reduced, thus increasing steering feel and alignment stability under load.

      Heavy Duty Construction. BMR Suspension proudly designs and manufactures their Subframe Chassis Brace right here in the USA. BMR's Brace features a triangulated design that ties key structural points together for an extremely rigid frame. This Subframe Chassis Brace is constructed from heavy duty 2-1/4" DOM steel and 1" x 1.5" rectangular tubing for exceptional strength. BMR then completes their Brace in a durable bright red powder coated finish for impressive good looks and long lasting corrosion resistance.

      Easy Installation. Installation is 100% bolt-on and all necessary hardware is included. A lift helps, but installation can be achieved with jack stands and a good socket set.

      Application. This red BMR Front Subframe Chassis is specifically designed to fit on the 2015-2020 GT and EcoBoost Mustangs. It does not fit on the V6 and GT350 models.

      Technical Note. This Subframe Chassis Brace is not compatible on the GT models equipped with Kooks Long Tube Headers.

        Make sure you get the updated design

        For those with the 2018-2020 10R80 automatic transmission, BMR has revised the design of the main cross member. It now has an indent so it doesn't interfere with the transmission cooling lines. The new product number is BMR-CB006R.

        Does what it's suppose to do!!!!

        This product by BMR does exactly what it's suppose to do. It gives that extra support at the front sub-frame. Looks nice, very solid built piece by BMR and easy to install onto the car. I definetly recommend using a lift to get under the car to install. Highly recommend this product for you S550 Mustang.

        Perfect look

        The BMR brace fit well and definitely added support for the front end and I highly recommend buying. I experienced only one small issue which involved the brace contacting the transmission lines. I had to use some spacers to create enough clearance to avoid transmission line damage. Otherwise great value and a must if you remove the strut tower brace as I did for fitment of a supercharger.

      For some reason it says this part doesn’t fit my GT350 but every other site including the bmr site says it will fit the GT350. I’d rather order from AM but I need to clarify that this is the same part first and not something different.
