The 2010+ Genesis Coupe rear chassis bar from Luxon connects opposite (left/right) parts of the frame together to increase the suspension's resistance to roll in turns. This high quality suspension modification reduces increased weight on the outside tires while hard cornering, which drastically improves handling as well as steering. It causes the body of the car to remain flat through a turn so that the weight stays distributed evenly on all four tires. Perfect for autocrossing or highly aggressive drivers. Please note this product may not fit with certain aftermarket exhaust applications.
