Restore proper suspension geometry with this adjustable lower rear control arm. The factory control arm can't compensate enough when lowering your Boxster, leaving you stuck with as much as 1/2" of toe in. The result is poor handling and rapid tire wear. This kit will provide the additional adjustment needed. The adjusting link has a left and right hand thread on each end. Rotating the link will increase or decrease the overall length of the arm. A precision Teflon lined spherical rod end replaces the compliant rubber factory bushing for improved suspension response and feedback, and also reduces toe changes during acceleration and deceleration. The result is improved stability and control. The complete kit comes as shown, including new Porsche outer tie rods.
