Factory subframe bushings are designed with soft voids to absorb road vibrations, but at the cost of a sloppy feel during aggressive driving. iE subframe Inserts fill these gaps with rigid aluminum, dramatically reducing unwanted chassis movement for sharper and more predictable handling feedback.

As a proper all-in-one solution, the included Dead Set Kit also fixes the factory flaw of oversized subframe bolt holes. These gaps allow unwanted movement and misalignment during hard driving. iE’s precision-machined aluminum collars lock the subframe in place by perfectly centering each bolt and creating a secure, press-fit connection.
