BMR Tubular K-Member With Lowered Motor Mounts Mustang GT 2005-2014/GT500 2007-2014

In previous videos, we discussed the benefit of taking weight off the front of your Mustang when you’re setting up for drag racing. A lighter front end is going to lift easier, allowing better weight transfer to the rear is going to increase your traction. On this 2013 Mustang GT, so far we’ve taken some weight off the front with a BMR Lightweight Radiator Support. Today we’re going to take waver ducks into the next level by removing the heavy factory K-Member motor mounts, replacing with these two-meter K-Member from BMR.

This BMR two-meter K-Member will fit your 2011-2014 Mustang GT. It’s available in the black hammertone finish shown here or a red powder coat. There are two different options for your motor mounts, stock height motor mount or they have a lowered motor mount if you want to bring the engine down a little bit into your engine bay. This will work with your stock A-arms. If you’re looking to save a little more weight, BMR does this for a two-meter A-arm as well.

For this installation, you need a Jack and Jack Stands or Lift and Pole Jack, ½” Impact Gun, 3/8 Ratchet, ¼” Ratchet, 22 mm Deep Socket, 19 mm Deep Socket, 18 mm Deep Socket, 13/16 Deep Socket, 17 mm Deep Socket, 17 mm Shallow Socket, 15 mm Deep Socket, 15 mm Shallow Socket, 13 mm Socket, 9/16 Shallow Socket, 7 mm Socket and assortment of Extensions and a Swivel, 22 mm Wrench, 7/8 Wrench, 19 mm Wrench, 9/16 Wrench, Torque Wrench, Hammer, Marker and Safety Glasses.

To start the installation, get the car off the ground or remove both front wheels. Once you have the car from the air, the first step is to disconnect the tire rod ends from the spindles. Then we’ll tap that through the spindle. I’ll disconnect the ball joint from the spindle and get the ball joint out of the spindle. Next we’re going to remove this bolt here from the steering rod. We’re going to mark it before we do so, so we know where everything goes and it goes back together. We’re going to remove these front covers here to give us more access to our steering rack.

Now we’re removing the lower K-Member brace. If you’re storing a Stock Radiator Support, these will be four 15 mm bolts. Since we have the BMR already in the place, the hardware is a little bit different. I’ll disconnect the electric steering rack. Next you want to move up the top and loosen the two nuts that hold the motor mounts on. They’re easy to get to from the engine bay itself. You need a pretty good extension with a 15 mm socket.

Once you have the motor mounts loosened up, you want to support the motor and transmission because now we can remove the K-Member. Right here in the front of the transmission is the best place to support it. You want to make sure you’re on the back side of this bar because this will come off with the K-Member. If you just start seeing it move upward, you’re good to know. There are eight total bolts holding your K-Member into your Mustang. There are two back here, one, two up top here and the same thing on the passenger side. Before we remove the last two bolts and pull up the K-Member, you want to get a jack on the front and it’s not a bad idea to get some help. The fact that the K-Member is on the heavy side, plus your steering is connected to it as well as the A-arms, to bring it down out of the car, it does have some weight to it.

We’ve already done a video showing you how to install long tube headers with the K-Member in place. If you decide to do long tubes, if you have the K-Member out like you have today, it’s a perfect opportunity to pull your factory headers off and put a set of long tubes on. This car currently has Kooks but we’re going to pop those off and install a set of JBA long tubes. Once we have the K-Member on the ground, we’re going to remove the steering rack. We’re removing these three bolts right here.

Since we’re planning on reusing our factoring A-arms, we’re going to remove those next. Here’s our stock K-Member next to our BMR tubular K-Member. We weight both of them with the stock one coming in at 48-1/2 pounds, the BMR only 25-1/2 pounds for a total weight savings of 23 pounds. Not only is it lighter, the tubular design gives us a lot more room to work underneath the car. Before we install the steering rack, we’re going to put the A-arms on. We need to get everything installed loosely before we tighten it up. Use the space to get the rears in place.

Now we’re going to install the steering rack. Now with a little bit of help we’re going to put our K-Member back into the car. You reconnect the steering shack as it goes up into place. I’m only going to put four of the mounting bolts in place for now. We may have to shimmy the K-Member a little bit to get the engine lined up. This might be hard to see in the cars. I’m going to show how the assembly works before we put it together. This top piece here and this pushing with that facing down, this goes on top of the K-Member. The washer, the other piece here, will go underneath the K-Member and sandwich the K-Member between the two bushings.

Then you’ll put your bolt up through the bottom into the factory motor mount bracket and then threat the nut on the top. Once it’s assembled, this will be your factory motor mount bracket here. This will sandwich between the bracket on our K-Member. Once you have the motor mounts done, you can install the rest of the K-Member bolts. Once we get them in place, we’re going to go back through and torque them all to 85 foot pound. You want to make sure your ball joint is sealed all the way up in the spindle. We’re going to reinstall the hardware for that. Tighten up the tie rod ends. Don’t forget to plug back in the electric steering. I’ll put the lock bolt in for our steering arm.

The BMR K-Member doesn’t have provisions for the factory chassis brace so the last of our installation is to reinstall the supply shield. We’re going to zip tight the rear of this in place to our Radiator Support. Reinstall your wheels and your installation is finished.

Because of some of the components we did unbolt for this installation, you want to get an alignment before you take your car on the road and actually drive it. Overall, our BMR K-Member fits great, gives us a lot more room to work and best of all, about 23 pounds off the front of our GT. Installation will take you around three hours. You’ll be back on the road in no time.
