The wishbone bushes for the E46 and the E46 M3, fitted to the rear of the front wishbone have a hard anodised aluminium outer shell with one of Powerflex’s unique low friction polyurethane centre bushes.

The polyurethane/aluminium combination creates a low friction rotating bush reducing the forces acting on the arm. Lower arm deflection has been decreased by reducing the compliant material within the aluminium shell. Results are less movement in the arm under cornering and braking, improving steering control and feel.

The PFF5-5601 is a premium performance upgrade to the previous standard bush PFF5-4601, making the new ones high performance offering greater precision for people wanting the very best from their E46 M3.
