Review & Install Video
Hey, guys, Stephanie with americanmuscle.com, here with an overview of this front subframe chassis brace from BMR for the 2015 and newer GT and EcoBoost Mustang. In this video, we're gonna discuss what this brace does and how it's designed to work, the materials and 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 a 100% bolt-on item that you can install with simple hand tools, and it's gonna be a one out of three wrenches on the difficulty meter. The BMR Front Subframe Chassis Brace is gonna be something that you should check out if you're planning on pushing your S550 to the limit and you're looking for a way to increase steering stability and give the K-member some more backing.This brace ties together a few points on the front of the car to support and stiffen the front suspension since there can be some deflection there. And it's gonna be for street performance, drag racing, and any handling application that does not have coaxial on two headers installed. This is for more of an extreme application, and it's not something that you can bolt onto a daily driver and notice right away. If you're looking to simply tighten things up in the front end, you can always check out some other suspension mods, like a sway bar upgrade. The most important thing about this brace is its functionality. It ties into front lower control mounts to the rear legs of the K-member. These areas are good to support, because the factory K-member and the lower control arm mount are very strong right from the factory, but they do still deflect and flex under extreme use. This deflection is gonna take away handling performance. So, if you think you're gonna be pushing your car hard enough to experience some of this deflection, this brace will help with that. That's why this isn't really a brace that you'll be able to bolt onto a daily driver and cruise around town and notice differences in your handling performance right away. This is more for those heavy-duty applications, because the factory components are strong in these areas with deflection only happening under hard driving. The design of this brace, by tying in the lower control arm mount and the rear legs of the K-member, reinforces the major areas of the K-member to reduce the deflection that can happen in these cases. Reduced deflection here means a better steering feel, 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, when you tie in these points on the chassis, you reduce deflection and get better handling results, but you aren't going to 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 no bushings at all, but those methods add NVH. A brace like this one here avoids adding NVH but still gets you the result that you want. Now, adding a brace to the K-member like this is going to open up some questions about fitment and, of course, long tube headers are going to be a concern. This brace will work the stock in very nearly all aftermarket systems, including most long tube headers. It will not work with Kooks long tube headers though, so just keep that in mind. If you happen to have a set of Kooks long tubes, you can check out the Steeda brace instead. This brace is also not going to work on the V6 model.As far as materials, 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 that's powder-coated for corrosion resistance. It also has CNC machine build aluminum spacers for you, and it's gonna come with your install hardware, too. Like I said before, this is 100% bolt-on, so it's going to use existing bolt holes. When it comes to price, you can expect to pay a touch below the $150 mark for this brace. There is an option from Steeda that's slightly more expensive than the BMR here, and you can always check that out as well. 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 positives here.Moving on to the install, like I said earlier, this is a direct fit item, so the install's 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 will make things easier. Your wheels will need to come off, and you're gonna need to pull the lower control arm bolts. The spacers will go into the subframe and then 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 on the hub and rotor assembly so you can line the bolts up and get them through. The 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 have pictures as well to help you guys out. Overall, this is a very easy install for anyone.Wrapping things up with the BMR Front Subframe Chassis Brace, this is a brace that's gonna tie together the rear of the K-member and the lower control arm mounting points to provide 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 americanmuscle.com.
The Platform Improver.
BMR works to ensure your high-performance 2015-2019 Mustang is stable on the track. 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. Have your cake and eat it, too! 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 black hammertone powder coated finish for impressive good looks and long lasting corrosion resistance.Easy Installation.
