      • Eliminates Chassis Flex and Twist
      • Triangulated Boxed Design
      • Weld in Design
      • Black Hammer-Tone Powder Coat Finish
      • Fits All 2005-2014 Mustangs
      • Made in the USA


      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.

      Fitment: 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014

        Convertible Must Have

        Trust me, the rigidness from this is truly amazing. Had a shop do it for me b/c I had about a 1/2-3/4 inch gap at the front weld point on passenger side (previously wrecked there). Shop welded a bracket to make up the difference. What a difference.

        No more flex

        Before when I would hit the breaks the car would compress , now it stays stiff and feels great during turns and take offs

        I had to replace out my rusted out convertible subframe braces and with the oem ones being outrageously expensive I decided to get these and I am really glad I did! Stiffened up the chassis big time. Big upgrade and it was cheaper than replacing those sub grade oem parts. It's a win win! So if u have a convertible and need to replace those rusted out chassis braces definitely don't think twice and get these. Highley recommended!!

        5 2005 GT - Weirdwillie Installation Time: Afternoon

        Great product and fit

        The quality and fitment of this product is top notch. I was worried that my early 2005 Mustang GT might have issues with the gas lines since a competitor product doesn't work due to the different line routing on early 2005 models but the BMR braces fit perfectly with no modification needed. The only issue I had is that I used jack stands (rear axle) and ramps (front tire) to do the welding and working under the car and welding is a pain. Also, one of the front mounts welds to thin metal on the unibody so it is tricky not burning through the thin metal to get a decent weld. If you a good welder (unlike myself!), you probably will have zero issues.

        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.

        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.

      Is this the only subframe connector I need? Does this subframe connector connect the front to the rear or just the front to center/rear to center? Thank you.

      • YES, THESE (WELD-ON) SUBFRAME CONNECTORS WILL DEFINITELY BE THE ONLY SF CONNECTORS YOU WILL EVER NEED. These subframe connectors connects the front to the rear and is very good quality and they come in RED also. The great thing about Weld-On SF Conn's is weld and forget. There are bolt-on SF Conn's out there but as the chassis (Body-Flex) flexes through time those will work their way loose. BMR has various Braces in Red also. If you end up adding braces along with your SF Conn's Please do your research on the types of braces for aftermarket exhaust compatibility & Tranny Air Scoops. Good Luck on future mods.
