Ford did a great job designing the '05 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 '05 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 BMR's 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.
BMR also answers your requests with specialized versions of thier K-members. BMR makes K-members for manual rack conversions, lowered motor mounts for more supercharger clearance, conversion K-members for traditional Windsor motor transplants, etc.
*All BMR S197 Mustang K-Members can be used on 2011+ Mustangs with the addition of 2005-2010 style power steering, or a manual steering rack kit.
