Steeda Mustang IRS Subframe Bushing Support System
These inserts support the original rear subframe bushes by filling their voids. Restricting subframe movement gives the rear suspension a more settled connection and helps reduce wheel hop. Steeda reports no additional noise or vibration.
The patented kit installs with basic hand tools and requires no permanent modifications. It is also part of Steeda’s IRS base pack together with the subframe alignment sleeves. European ECE approval is stated by the manufacturer.
