    Eliminate Body Flex. Did you know that you can improve the handling performance of your Mustang on the street, track and strip by installing a set of BMR Subframe Connectors? The unibody construction of the S197 Mustang can actually twist or flex under load negatively affecting its handling performance. BMR Suspension specifically engineered their Boxed Subframe Connectors to add the additional structural rigidity needed to eliminate this chassis flex to improve your handling performance. A set of Subframe Connectors are one of the first modifications that should be done to any unibody vehicle, especially ones that see their fair share of spirited driving.

    Triangulated Design. BMR Suspension proudly designs and manufactures their Subframe Connectors right here in the USA. BMR's Connectors feature a triangulated design that ties key structural points together for an extremely rigid frame. This Subframe Connector is constructed from heavy duty boxed 1.5" x 2" main tubing with both 1" x 2" and 1" gussets and 3/16" weld plates for exceptional strength. BMR then completes their Subframe Connectors in a durable bright red powder coated finish for impressive good looks and long lasting corrosion resistance.

    Weld-in Design. BMR engineered their Boxed Subframe Connectors to be welded into place for additional strength and rigidity. Being a weld in design makes BMR's Connectors far superior to the competitions flimsy bolt-on connectors that can become loose over time defeating the whole purpose of installing the connector in the first place.

    Application. These BMR Suspension Subframe Connectors are designed to fit the 2005 to 2014 Mustang Coupes, including the V6, GT, Bullitt, BOSS and Shelby GT500 models. Will also fit convertible Mustangs if the factory rear bracing is removed before installation.

        5 Top Rated Questions

        Do you lose any ground clearance with these? Can you reinstall the (convertible) braces you have to remove to install these?

        Can these work with the Steeda Ultra-Lite Low Profile Chassis Jacking Rails?

        • These will work together yes.

        Will these need to be welded on the car or can you just bolt these on? Also, are these a direct fit or would need some modification?

        • The subframe connectors are designed to be welded in, not bolted in. These would also not require any modification aside from cutting the fuel line cover to fit once installed.

        Will these need to be welded on the car or can you just bolt these on?

        • This subframe kit is designed to be welded on the vehicle which will allow them to be more secure without the worry of them becoming loose over time.

        Helpful (0)

        Can you use a trolley jack on these and not damage the rockers?

        • The BMR Boxed Subframe Connectors are not designed to be used as a lift/jack point. We recommend a quality set of jacking rails for adding a lift point.

            Better than OEM subframe conecctors

            Look good and definitely an improvement over the rusted out OEM subframe connectors on my 2006 Mustang convertible. Only gave four stars because my installer claimed it took six hours to install them. Maybe it did; that's what he claims.

            Subframe connector

            Instructions that I got on the website really doesn't show where to weld. Over all they look like do the job.

            Outstanding product

            These sub frame connectors are a great add on for your Mustang. They are well constructed and fit perfectly. A friend of mine and I installed these connectors while the car was on jack stands. That worked, however I would recommend if possible do install while the car is on a drive on rack Welding overhead is much more difficult. To support the connectors instead of using a floor jack you could use a transmission jack to facilitate the installation. The car is much stiffer now resulting is a much firmer frame while either launching off the line or cornering at a higher speed than before. This was the final add to my pony's suspension since I already had the BMR K member, chassis brace, radiator support, front control arms as well as an adjustable rear upper and lower control arms along with a BMR adjustable pan hard bar with a pan hard bar support. I highly recommend these sub frame connectors as well as other BMR suspension parts.

            Body much stiffer!

            Like most BMR products, these subframe connectors are very high quality and fit! Install was easy and handling is much better now!

            Replaces OEM and Improves Handling

            5 Stars! I didn't see these as a performance enhancement, but if so that would be a bonus. I was hoping that these would be a suitable replacement for the factory sub frame braces on the convertible ( which rust out and are quite expensive to replace). They are actually an improvement- the car handles better, You can see a noticeable difference- it stays flatter in corners with no rolling or leaning. Feels like my SVO did when it was new. Great upgrade for way less than factory original parts ( and they look good when you are under the car!).

            Great Product

            The convertible support bars on my Mustang were rusted and the one the passenger side had rusted all the way through. I removed them and had the BMR connectors installed (by someone who can weld better than me) and the handling is great now. I expected a difference but these surpassed my expectations. The handling is so much tighter and responsive now. I highly recommend to anyone with a convertible.

            Best addition for convertible

            These are awesome. Install is easier with a lift. I removed the factory Convertible bracing and welded these in place. The car just feels more solid and less body shake when hard accelerating. Highly recommended for both coupes and verts!
