PFR57-106 has been designed to replace the rear trailing arm front bushings where the arm locates onto the chassis. These bushings are no longer available from Porsche unless you buy the complete arm at a cost of over $1,000.00. The RS model has a stiffer bushing fitted over the standard non RS models, the Powerflex bushing will upgrade the standard bushings to a similar stiffness to that of the RS version. PFR57-106 comes with Oil Lite bearings to allow the arm to pivot freely allowing the suspension to work with no loading from the bushing with positive location.
