PFF5-2701 Front Radius Arm Bushing is made using our Black 95A durometer material and supplied with zinc-plated outer shells to increase stiffness over OE by 7.5x at 3mm load displacement, by controlling longitudinal wheel movement under braking and cornering for more precise handling and improving longer-term bush durability to extend tire life. PFF5-2701 is only compatible with F34 GT xDrive models.
