Subframe Inserts
Stock subframe bushings are soft by design to absorb road vibrations, which can cause sloppy handling under aggressive driving. iE Subframe Inserts fill these voids with precision-machined aluminum, dramatically reducing unwanted chassis movement. This delivers sharper, more predictable feedback through every turn.
Dead Set Kit
Factory subframe bolt holes are often oversized, allowing misalignment during hard driving. iE’s Dead Set Kit uses precision-machined aluminum collars to center each bolt, creating a secure, press-fit connection. This locks the subframe in place, eliminating movement and improving stability.
