    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, we 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. One of the areas team Steeda wanted to focus on was the rear IRS subframe.

    As you have seen with our IRS Subframe Bushing Support System, it limits the movement of the subframe by filling in the voids of the OE bushings. With Steeda’s IRS Subframe Support Brace, we have taken the S550 rear suspension to another level!

    Built in-house from 4130 chrome moly steel and powdercoated silver metal flake, this part isn’t only strong - it also looks great under your new Mustang! What we did was tie together 3 very important points on the S550 chassis. We utilized existing threaded holes in the rocker panel (the strongest part of the body) 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.

    Also, unlike competitors kits that have not been released yet and only replace the factory bracket, our Steeda kit supports that bracket while connecting to 2 additional locations, therefore providing twice the support! Best part about this kit is it uses all existing holes in the chassis so the car doesn’t have to be modified in any way and adds no NVH whatsoever. :)

    Very, very nice. This looks to be a really easy installation process?

    I think I will have to do the bushing supports and this brace. Nice job Steeda! Went to track last night and wheel hop was bad.

    David, what is the combined weight of the two bars plus bolts, please? Any clearance issues possible or is it tucked away? This looks like it might be yet another good thing to do.

    Just to clarify this kit comes with two braces for a left and right side installation?

    With these and the support, inserts, bushings installed, can the sub frame still be possibly mis-aligned?

    This has nothing to do with subframe alignment, so if yours was mis-aligned from the factory then the only way to fix it is by picking up our IRS subframe alignment kit: http://www.steeda.com/steeda-s550-mustang-irs-subframe-alignment-kit-2015-all-555-4438/

    I'd recommend the subframe alignment kit paired with our inserts - if yours was off-center then your car will need to be aligned post-install. Then I'd recommend our vertical links and these Steeda IRS support braces.
