Description
The Steeda IRS Subframe Braces add rigidity to your S550 / S650 Mustang’s rear end as a simple bolt-on upgrade.. 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, we knew there would be an excellent opportunity to capitalise 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 moves, twisting or vibrating when it should be stationary is a significant problem. One of the areas that Steeda wanted to focus on was the rear IRS subframe.
As you have seen with our IRS Subframe Bushing Support System, the movement of the subframe is limited by filling in the voids of the OE bushings. With Steeda IRS Subframe Braces , we have taken the S550 Mustang rear suspension to another level!
Our Steeda Mustang Rear IRS Subframe Braces for the 2015 Mustang GT and EcoBoost (non-convertible) are built in-house from 4130 chrome moly steel and powder-coated silver metal flake; this part isn’t only strong – it also looks great under your new Mustang! What we did was tie together three crucial points on the S550 chassis. We utilised 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 adds rigidity that was lacking in the rear and more control of the whole car.
Also, unlike competitors’ kits that only replace the factory bracket, our Steeda kit supports that bracket while connecting to 2 additional locations, therefore providing twice the support! The best part about this kit is that 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.
