Powerflex 24 mm Front Sway Bar Bushings for Porsche 996/997/986/987

Support a 24 mm front anti-roll bar with the Powerflex bushings specified for these Porsche 911, Boxster and Cayman platforms. The bushes locate the bar in its chassis mounts while allowing it to rotate, so the actual bar diameter is the first detail to measure before choosing the set.
