Why Chassis Reinforcement Matters

Factory chassis flex is a common limitation on older performance platforms like the E46. Adding a balance bar or anti-roll brace redistributes load more evenly across the chassis, reducing unwanted body roll during cornering and improving the feel of your steering and suspension.
