SuperPro have developed and released the Front Arms as a Performance upgrade from the standard OEM style rubber bushings and ball joint. The new SuperPro arms allow for adjustment to achieve additional caster independently on each side of the vehicle. This feature is best utilized to correct a slight pull and to enhance directional stability and feel. The OEM bushings are fairly soft and the SuperPro bushings reduce the arm movement and increase stability under braking, cornering and will increase tire life. The SuperPro Alloy Lower Control Arm is an M3 style arm with a fixed camber increase fitted with a heim style Bushing to complete the package. The SuperPro bushings allows full articulation and movement without binding and with no increase in noise, vibration or harshness.
