Steeda Rear IRS Subframe Support Braces for all 2015, 2016 and 2017 Fastback Mustangs.
As you may have seen, Steeda's IRS Subframe Bushing Support System solved many problems with a quick and easy solution that limits the movement of the subframe by filling in the voids of the OE bushings. Now with Steeda’s IRS Subframe Support Braces, they have taken the S550 rear suspension to another level!
The Steeda S550 Mustang Rear IRS Subframe Braces for 2015-2017 Fastback Mustang V6, EcoBoost or GT are built in-house from 4130 chrome moly steel and powdercoated silver metal flake, this part isn’t only strong, it will look great under your new Mustang! What they did was tie together 3 very important points on the S550 chassis. Steeda utilized existing threaded holes in the rocker panel and connected that to the front mounting location of the IRS subframe and the rear mount of the lower control arm and toe link. Connecting these 3 points together not only adds rigidity that was lacking in the rear, but also more control of the whole car.
Features and Benefits:
- Better Handling for More Stable Cornering
- Limits IRS Sub-Frame Movement
- No Permanent Modifications Necessary
- No Added NVH (Noise, Vibration and Harshness)
- 50% More Connecting Points
- Reduces Wheel Hop
- Made In The USA
*Will NOT work with Convertible 2015-2017 Mustang Models.
With the release of the new S550 Mustang, Steeda knew that addressing the IRS system would be a top priority. Being the first production Mustang with an IRS since the 03/04 Cobra’s, they knew there would be a great opportunity to capitalize on Ford’s new piece by giving it the Steeda advantage. As with any suspension system, deflection is an issue if it’s present. Anytime a piece is moving, twisting or vibrating when it should be stationary is a major problem. And Steeda came up with a simple and inexpensive solution to a big problem.

Will these fit on a GT equipped with the Steeda jacking rails?
Hi! can this fit the ecoboost?
I plan to install AirLift performance suspension on my 2015 GT w/ PP, are these braces compatible and would you recommend, and I do plan on tracking my car as well.
Hi, I Own a 2015 GT with Eibach pro plus system setup to the middle Hole front and rear. I have a case of wheel hop when starting pretty fast. Whats the best effective way to get rid of wheel hop? What do you recommend?
I've read that some have had these braces welded in. Is that recommended?
Does this do the same as a rear "sway bar?" Does the Steeda K bar act as a front sway bar? Do you know if the GT shock tower brace will fit the V6? 2016 Mustang V6. Thank you, Tom
Is there a similar product that will work on my 2016 pp conv GT ?...

These Steeda Rear Subframe Braces are made here in the USA of high quality chromoly steel. They're going to fit your fastback, only they will not fit your convertible. These are going to bolt onto your chassis, have no increased noise and vibration, and really hold the subframe tight to let you put power to the ground. For this installation we're going to need a lift or a jack and jack stands, 3/8 ratchet, 15 millimeter socket, 10 millimeter allen key, and a torque wrench.
The Steeda rear Subframe Braces are going to mount here, and on the bolt in the center, and then over here on the subframe as well. The first step of the installation is to remove this rear factory bolt. Next we're going to take the supplied threaded plate and slide it right in the subframe through this opening here so we can install the hardware. Now we're going to put the braces up into place and loosely install the hardware. They are side specific, and can only go one way. Install the factory hardware in the front opening here and the bolt supplied by Steeda in the rear. The front bolt's going to go into the threaded plate we installed earlier, get that started. I'll put this bolt up into place here, may have to pull on it a little bit to get it to go through, then reach over the top and install the nut. Once we get that started we can go back through and tighten everything down. Now we're going to torque them down. The front three bolts are going to 45 foot pounds, the back two will be 55. We're going to repeat the process on the other side and your installation's finished.
By tying in three key mounting points, the rear subframe brace from Steeda doing a great job of keeping the subframe planted which will allow you to put power to the ground instead of causing wheel hop. The whole installation's pretty straightforward, will take you around an hour so you'll be back on the road in no time.
