The ball joint design allows the control arm to articulate freely with minimal resistance, delivering sharper steering response and more consistent suspension geometry. When installed on F22 and F3X models, this arm increases negative front camber by approximately 0.5 degrees by pushing the lower portion of the wheel outward, while also being slightly lighter than the factory control arm.
These front lower control arms (also known as “wishbone” by BMW) is a direct fit for the F80 M3, F82/F83 M4 and serves as a popular performance upgrade for the F22 2-Series and F3X 3/4-Series. Unlike standard arms that rely on soft rubber bushings, the M3/M4 wishbone features sealed inner bearings, providing superior precision, durability, and reduced deflection under load.
KTA286 is heavy duty adjustable control arm kit designed to allow for increased range of camber adjustment. Low compliance bushings are used to minimise NVH and maximise longevity. Left-right-hand thread adjustment turn-buckle nut allows for easy on-car adjustment.
Protective powder coating acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
This makes it an ideal upgrade for track and autocross applications, improving front-end grip, turn-in, and overall handling without compromising reliability.
Designed with the installer in mind by reducing the need of specialised skills, tools and equipment.
