991 C2/C4 Rear Suspension Upgrade Kit

These precision Adjustable control arms and monoballs are direct replacements for the factory arms. The arms are fully adjustable in length for an increased range of camber adjustability and alignment fine tuning. The Precision Teflon lined spherical rod ends and monoballs replace the compliant factory rubber bushings for suspension response and feedback. Camber and toe changes associated with hard cornering and decelerating are significantly reduced. The results are improved stability and control, and faster lap times. The adjusting links have a left and right hand thread on each end. Rotating the link will precisely increase or decrease the overall length of the arm. Links can be purchased individually or as the complete kit.  Rod end boots are available (below) to seal out any dirt and moisture that get in contact with the links.  Fits all 991 C2/C4 without toe steer.
