Overview
Solidify the IRS on your 2015+ S550 with Steeda’s HARDCORE Subframe to Body Bushing Kit. CNC machined and made from billet 6061-T6 aluminum, these mounts eliminate all subframe movement, improving traction and handling while also reducing wheel hop. The unique cut-outs ensure that this is the lightest kit on the market while at the same time not sacrificing strength. The Steeda HARDCORE S550 Mustang Subframe to Body Bushing Kit is a must for the driver hitting the track or strip and want to lock the IRS in place.

— Why we stock Steeda
OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.
Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.
We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
