Product Description

Steeda IRS Subframe Bushing Support System for all 2015, 2016 and 2017 Mustangs.

Steeda has been extremely busy with the development of new products for the new 2015-2017 Mustangs. And with that, one of their main focuses has been a turn-key, easy to install wheel hop/IRS subframe solution for your S550. And we believe they hit the nail on the head with their new IRS Subframe Bushing Support System!

Steeda's IRS Sub Frame Bushing Support System is designed to fit your 2015-2017 V6, EcoBoost or GT Mustang and provide a much more solid feel with no increase in NVH at all. The Steeda IRS Sub frame bushing support system will also eliminate rear sub frame movement that is notorious in the S550 Mustang. A stiffened subframe will allow a significant increase in traction at the rear wheels and help eliminate almost all noticeable wheel hop.

Features and Benefits:
- Fits All 2015-2017 V6, EcoBoost and GT Mustangs
- Significant Increase in Traction
- Does Not Cause Unwanted NVH (Noise, Vibration and Harshness)
- Easy, Do-It-Yourself Installation
- Requires No Permanent Modifications
- Completely Reversible Back to Stock
- Patent pending with a Lifetime warranty from Steeda
- Includes All Necessary Hardware and Detailed Installation Instructions

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!

Steeda IRS Subframe Bushing Support System 2015-2017 is rated 4.1 out of 5 by 9.
Rated 3 out of 5 by from Works, but fiddly install Installed at same time as Steeda braces, and together they cured low-speed corner chatter on tight turns, which was the point. Rear seems to hold road surface better in all circumstances. HOWEVER, my S550 came with Track Pack, which may use beefier bushings at lower rear position; install was huge pain, really fiddly, and was never sure that bolts didn't cross thread when finally tightened down. Have put zip ties around lower rear pieces to help them stay together incase the bolts were cross threaded. Overall worth it, but at the time of install, after spending 2 hours on the first side, I really had to take a break.

Rated 4 out of 5 by from Good but not great. This does cut some of the hop but I would say probably 30% to 40%. For the most part it is a simple install with the exception of the two part bushing. No where near as easy as Bill makes it seem. That stiffener squeezes between two pieces of metal that was particularly tight on my vehicle. The lubricate helped but the screwdriver didn't really do much and was a waste of time. Finally resorted to using Channel locks to squeeze and maneuver it in place. Went much, much faster. Additionally, I did the install with jack stands and the tires on. Did one side at a time and one bolt at a time using the other bolt to lower the bushing of the removed bolt in order to get the upper stiffener in place. That part went very smoothly

Rated 5 out of 5 by from Great upgrade The bushings really help the rear end feel attached to the car. It no longer gives me the feeling like the entire thing would fall off, by itself its not a solution to the wheel hop plage, but it makes a drastic improvement. Cudos Steeda!

Rated 5 out of 5 by from Definitely worth the purchase. Eliminated my wheel hop when accelerating from a stand still. The rear end also doesn't sink drastically like it use to when accelerating and it doesn't jump as hard when shifting through the gears. Overall I'm very happy with my purchase. The install only took about an hour for both sides. Not very difficult but the rear lower bushings can be a challenge.

Rated 4 out of 5 by from Installed the Steeda IRS Subframe Bushing Support I did install these on my 2015, they did stiffen the rear a bit and did reduce but not eliminate wheel hop. They did take a bit longer to install than the "about an hour: it took me an ASE master tech using a hoist about 90 minutes to do the install (it was the first time I had installed these). They are worth the cost and effort, but don't expect a miracle. I am now installing the vertical links and a few other components help address the rear suspension squirm issues when cornering hard.

Rated 5 out of 5 by from Got more than I expected Put this on my 2015 PP 5.0. Really helped with the wheel hop(when combined with the diff bushings). What didn't expect was the huge change in the stiffness of the rear of the vehicle. Guess I need to upgrade the front end now.

Rated 5 out of 5 by from Great Mod Already had the k member brace and subframe braces, added the subframe bushings along with the sport linear springs, and verticals links and wow what a difference. Much smoother, feels planted , much better when shifting hard, no nose dive and less bouncy. (In my opinion the PP springs are super bouncy). The only item not on my car are the rear toe links don't know how much difference it would make but overall very happy with the result as a whole package. Rear 2 piece is a pain to install but not impossible.

Will the bushing raise the stance

Will I need to get an alignment after the install?

Asked by: TMCraig
It is not necessary but anytime a suspension component is moved or replaced the alignment should be checked.

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?

Asked by: Mustang Carolee
Did not change mine at all.
Answered by: fatty239
Date published: 2016-04-26

Does installing the bushing support system raise the rear height of the car any, perhaps just by as much as the bushing thickness?

Asked by: Nun of Diego
There wouldn't be any noticeable difference in ride height.

Steeda IRS Subframe Bushing Support System 2015-2017 Video Transcript
By Bill Tumas: It's no secret by now that wheel hop is definitely an issue with the 2015 Mustang. Many people believe that the wheel hop is mainly caused by flex in the subframe where it's attached to the chassis due to the soft mounts. Steeda has come up with a very unique way to address this using their subframe support system, which we're going to install today on the Yassen’s 2015 Mustang GT.

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.
