The full breakdown.
Overview
Maintain control of your GT350 or Mach 1 and prevent it from losing traction due to wheel hop with this IRS bushing support system from Steeda. This is one of the first and most simple steps that should be taken to eliminate wheel hop. It is recommended that you also install the Steeda subframe alignment kit at this time because you will already be working in that area.
Eliminate subframe movement. The Steeda IRS subframe bushing support system eliminates the rear subframe movement that is notorious in the S550 Mustang platform. Stiffening the subframe and preventing movement is the way to reduce and eliminate the troublesome wheel hop that plagues the Mustang when launching or taking tight corners.
Enhanced road-feel. Installing the Steeda bushing support kit gives the driver a better feel for the road, letting the driver feel connected to the car. This makes spirited and track driving more enjoyable and more responsive.

— 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.
