The SuperPro Quick Fit Traction Pack for the 2008 Pontiac G8 pairs rear differential mount bushings with rear subframe insert/supplement bushings to reduce differential and subframe movement and improve traction at launch and on corner exit. The kit uses insert-style bushings for faster, reversible installation, includes void fillers to suit OEM bushes, and upgrades rear subframe and differential mounting points for more consistent traction.
