Deflection of the factory rubber bushing can result when it’s under heavy load. This can create steering wobble under heavy braking situations, an unwanted condition. Fall-Line presents its BMW upgrade with its F8X M2 Competition / M3 / M4 Front Mono Ball Conversion Kit, to remove this problem and allow for smooth movement of the thrust arm through its range of suspension travel, resulting in smooth steering without any unanticipated wobble or other steering issues. You can order this awesome upgrade from Olsen Motorsports today!
