KTA383

Lower Control Arm and Tension Strut Arm Kit

Whiteline KTA383 for the BMW F22 2-Series and F3X 3/4-Series is a set of four complete arms designed to resolve common front-end issues. Due to the high performance of many BMW models, the original rubber tension strut arm bushings are subjected to significant load and typically have a limited service life. Additionally, many owners lower their BMW using lowering springs or coilovers, which can introduce front-end geometry issues that require correction. For ease of fitment, these alloy tension arms come complete with sealed ball joint ends and adjustable synthetic elastomer bushings. These allow for ±0.5 degrees of caster adjustment, improving straight-line stability, enhancing steering feel, and increasing front-end grip on corner entry. The included F8X M-car upgraded front control arms feature sealed inner bearings to provide superior precision, durability, and reduced deflection under load. They add a fixed 0.5 degrees of negative camber by pushing the bottom of the wheel outward and weigh slightly less than the stock F22/F3X control arms. This makes them an ideal upgrade for track and autocross vehicles that demand increased negative front camber.
