Eliminate Body Flex. Subframe connectors are one of the first modifications that should be done to any uni-body vehicle. A set of BMR Suspension subframe connectors will add structural integrity to improve handling performance and stop power robbing chassis flex making sure you get all your pony's to the pavement.

Triangulated Design. The BMR Suspension Mustang sub-frame features a trianguled design that ties key structural points together for an extremely rigid frame. Made in the USA from heavy duty boxed 1.5" x 2" main tubing with both 1" x 2" and 1" gussets as well as 3/16" laser cut weld plates, BMR completes their subframe connectors with a black hammer-tone powder coat finish for durability and good looks.

Weld-in Design. The weld-in design of these BMR Suspension boxed steel subframe connectors is far superior and stronger than the flimsy bolt-in connectors available from the competition.

Application. The BMR Suspension Subframe Connectors are designed to fit the 2005 to 2014 Coupe Mustangs, including V6, GT, Bullitt, and Shelby GT500 models. Will also fit convertible Mustangs if rear bracing is removed.

Are these parts a replacement for the factory "rear to front" support braces of a convertible mustang? Or do I have to install the factory support braces after installing these one, too?


Do you have to remove carpet to weld these box style connectors in?

Will this fit with an x-pipe? I have a 2012 v6 coupe, will this fit with a bbk x-pipe, part #1814?


  • Yes these will fit with your X-pipe that you have on the car. Your mid-pipe will not interfere where these weld into the car. These weld onto the car from the frame out to the pinch welds of the car so they don't come close to any of the exhaust work.

    The Single Best Upgrade I've Done So Far

    i decided to add subframe connectors after some friends recommended them. i was a bit weary at first b/c the new s197 body is alot stiffer than previous mustangs i have driven, but i'm very glad i did this. i had them welded into place by a local shop, and the changes were noticed immediately. 1 - cabin noise was much quieter especially while crusing 2 - steering feedback and response was alot better 3 - launches are much more solid and wheel hop was severely reduced 4 - body flex was almost completely reduced. note: the shop did have to cut the bolts to which the brake line harness attaches, which is why i gave it a fit rating of 4/5

    Good Product

    These sub frame connectors a very nice. There is one major problem but easily fixed. The screw studs that hold the emergency brake bracket are too long. I highly recommend cutting the studs to a length of about 1". Mine were about 2" long and were rubbing against the fuel tank which is plastic. Luckily my friend noticed this or it could have started a leak. Other than that issue, the connectors are very nice. Install is absolutely no fun if you do not have a lift. If you don't have a lift I recommend having them professionally installed. I rolled around on the ground underneath the car for many hours. As soon as you go over the first bump you will notice how much stronger/stiffer the car feels.

    A great part for my mustang

    I always wondered how much was left on the table by Ford. These simple brace's made my car feel connected, it gave me more confidence and the car felt tighter. They should almost be required from ford. The quality and finish from BMR was great. I will always make subframe connectors one of my first mods from now on.

    A bridge is only as strong as its Foundation

    These WELD-ON BMR's on my 14 GT are awesome I had JBA's on my 93 COBRA. They are a necessity if you are doing serious suspension and HP upgrades.

    Subframe Connectors

    This is absolutely the first thing you should do to your car. This makes the car so much stiffer and eliminates all the rattles and squeaks. This will help your car keep a firm straight body for the rest of it's life. There is no change in ride quality either as some may claim. The new cars may be stiffer, but they are still not stiff enough. You will notice this modification and it is worthy every penny.

    Worth the money you can feel the difference

    The conneters are good looking finsh, but the fit was poor and had to add spacers on the passager side for a even fit. I tig welded it in and it looked ok. It is worth the money but would have liked a better fit even if it was more cost.

    BMR subframe connectors install.

    Came on time as shipped. Packaged very well. No dents or scratches. Good instructions. Easy to read and we'll illustrated. Took a complete afternoon to install in my garage. Would have been much easier with a hoist. No harder than expected.

    No more body roll

    I picked the BMR subframes based on simple physics. Triangular structures are meant to impart strength, and that is exactly what these have done to the chassis of my 05. Had these bolted in and then welded on by a local shop for next to nothing. Shop had to cut the bolts on the parking brake bracket, other than that very straight forward install. The difference is incredible, car no longer feels like a cheap roller coaster ride when taking corners at speed. Feels solid and much more predictable. Car transfers weight better during a hard launch which has reduced wheel hop and improved grip. By far the best thing you can do for your S197 suspension. Not to mention in the event of a crash these things can literally save your cars life by preventing damage to the subframe of the car. Provides multiple good jacking points to lift the car as well. If you don't have these yet you need to get a set ASAP, make sure to weld them on.
