Steeda Rear IRS Subframe Support Braces Ford Mustang Coupe 2015-2021 555-5754 | Vivid Racing
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 Braces, we have taken the S550 rear suspension to another level!
Our Steeda S550 Mustang Rear IRS Subframe Braces for 2015+ Fastback coupe Mustang 5.0L GT, 5.2L GT350, 2.3L EcoBoost, and 3.7L V6 fastback coupe (non-convertible) is 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.
Features:
- Better handling for more stable cornering
- Limits IRS sub frame movement
- No permanent modifications necessary
- No added NVH
- 50% more connecting points
- Reduces wheel hop
- Lifetime warranty
- Installation does not require removal of cradle
- Installation Guide
- Ford S550 Mustang Coupe 2015-2021 (Also fits the S550 GT500)
