Cusco Strut Tower Brace Front OS-Type BMW E46 3 Series 1998-2006
The Cusco Front Strut Tower Brace OS-Type reinforces the front chassis on BMW E46 3 Series models from 1998 to 2006 including sedans coupes convertibles and hatchbacks. This bolt-on brace ties the strut towers together to cut down flex during hard cornering for quicker steering response and flatter handling. Drivers notice tighter turn-in and more feedback from the suspension right away.
