The Steeda 2015-2017 Mustang IRS Sub Frame Bushing Support System for your S550 V6, EcoBoost or GT is made from CNC machined 6061 aluminum. This support system is very easy to install, with basic hand tools, even on jack stands in your driveway or garage. As an added benefit, this bushing kit does not require any permanent modifications to your car and installation can be reversed just as simple as it was installed.
When completely stock, your entire rear IRS subframe assembly will move around under acceleration, braking and even more so when slamming gears or spirited driving. This is a huge concern due to the fact that every single rear suspension piece is connected to your rear subframe. Every suspension component is moving around so violently that it makes it very hard for your suspension to work properly and keep the tires planted on the pavement for traction the way it was designed. These issues can cause unwanted changes in camber and toe which leads to unpredictable traction and control, resulting in handling issues.
Eliminate unwanted wheel hop and IRS subframe movement and order the Steeda IRS Subframe Bushing Support System for your 2015, 2016 or 2017 Mustang from CJ Pony Parts today!

Will I need to get an alignment after the install?
How long do you think it would take the average guy with a 2 post lift to do this upgrade?
Will the bushing support system change the height of the rear of the car? I mean like even an inch or perhaps just the bushing thickness?
Does installing the bushing support system raise the rear height of the car any, perhaps just by as much as the bushing thickness?
Would you recommend subframe bushings with Air Lift Performance suspension on a 2015 GT w/ performance pack?
This is Steeda IRS Bushing Subframe Support System. Based on what's going to happen is these billet inserts are going to be installed on the factory bushing locations, and are going to stiffen up the rear subframe. That's going to eliminate wheel hop, but at the same time cause no increase in noise or vibration. This is going to fit all 2015 Mustangs.
For this installation you'll need a jack and jack stands, or a lift and a pole jack, 1/2" ratchet, 21mm socket, 6" extension, torque wrench, flat head screwdriver, and 5/32 Allen key.
The Steeda bushing support system is going to mount on the four mounting locations where the subframe's going to mount to the chassis. One here, one in the front section here, and then two on the other side. You'll want to start by supporting the subframe. We're going to do one side at a time. Once you've supported the suspension with a jack you can start by removing the bolts. We're going to start with the rear. Before we can remove the front bolt these two small bolts and the bracket have to come off first. Now we're going to slowly lower down the subframe. You don't have to come down too far, just enough to get up inside there.
You're going to take the thicker spacer, it's going to go on the top. If you look, it's actually a cutout. You turn it and it'll drop into place when you have it in the right spot. The lower spacer has these cutouts here to go around these edges. Slide it on and move on to the rears. The upper's going to be the same as the front. There's going to be a cutout, you're going to lay it right in there. Make sure you use the thinner one for the rear, the thicker one goes up front. Lay it in the cutout, and now we can install the lower.
The lower rear is going to be a two piece bushing. What you want to do is separate it first. When you install it these notches are going to be facing upward. We're going to start by installing the small piece. We're going to spray a little lubricant, make our life a little bit easier to get it in there. I'm going to start from the front and sort of turn it into place. A small screwdriver will make it a little bit easier. Now you can put the other piece in from the outside. Then we'll tighten the bolts here to draw the two pieces together.
I have the bushings in place, we can lift our subframe back up to the chassis, and then bolt it back in. You need to get it close, but don't tighten it all the way until we get the front in, and then we'll torque them all down. We're going to torque the bolts to 129 foot pounds. You'll want to repeat the process on the other side, and then your installation's finished.
The Steeda bushing support system's fairly easy to install. It requires no permanent modifications, and it'll do a great job of keeping the subframe planted to the chassis of the car, which it'll definitely improve wheel hop. Overall the installation will take you around an hour, so you're back on the road in no time.
