Steeda Mustang Adjustable Diff Bushing Insert System (2015-2024+)

Excellent quality

I have installed Street Urethane Diff Bush kit to my GT, and specifically the red bushings. The have enhanced the IRS base pack's performance and they work very well as combination. No vibrations appeared, though the sound of the differential spinning is a bit more noticeable inside the passengers cabin, and clacking sound of the engage/disengage of the automatic gearbox is more noticeable, mostly in the low speed downshifts when coming to a complete stop.

Must have!

Good quality. Big difference in car handling.
