Overview

Alloy Arm Kit by SuperPro

SuperPro F20 & F30 series BMW Front Control Arm and Radius Arm set is offered 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, or to simply maximize positive caster for improved grip and feedback.

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 M style arm with a fixed camber increase fitted with a hyme 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.
