Whiteline rear crossmember outer mount insert kit for 2003+ Pontiac GTO replaces worn subframe bushings to reduce crossmember misalignment and movement, improving rear-end feedback and cornering stability. Whiteline's synthetic elastomer resists oil, grease, ozone and weathering; the bonded design and dampening voids optimize strength and reduce harsh shocks. An install guide is included for motorsport-ready applications.
