Ford did a great job designing the 11-14 Mustang. Everything comes apart so easily, it almost seems like it was designed by racers. To some, a tubular K-member may seem like a complicated and difficult installation, however in the '11-14 Mustang it can be done in 2 hours with hand tools!
BMR's tubular K-member uses an integrated mount system, saving up to 5 lbs. over the competitions' designs. The OE K-member with motor mounts weighs 44 lbs. while the integrated design weighs only 24 lbs., a 20 lb. weight reduction. Designed to be used with BMR or factory A-arms and spindles. Fits V6 and V8 models.
NOTE: BMR K-member replaces the heavy OE hydraulic motor mounts with high durometer polyurethane bushings resulting in increased noise transmission into the body. These bushings are designed for minimal flex and are identical in size and durometer to what is used in Prothane and Steeda's billet motor mounts (the only difference is that they are integrated into the K-member design) It is important to note that decreased motor movement from stiffer motor mounts will create additional noise and vibration into the body.
I've done the majority of my aftermarket mustang parts shopping at American muscle, recently finding out about this website I'd just like to say it is a great experience to shop here, the lay out is easy and simple to navigate, and you have thousands of parts that no other website has. The shipping is very fast and all te updates are great. I will be doin much more shopping with y'all, so thanks for being so badass haha
