Powerflex PFF5-4102 Front Lower Control Arm/Wishbone Inner Bushes - BMW 4 Series xDrive F32 F33 F36 (Coupe, Convertible, Gran Coupe) - Polyurethane Arm-to-Chassis/Subframe Bushing Kit - AWD F3x Suspension Upgrade - Pair

Powerflex PFF5-4102 Polyurethane Wishbone Inner Bushes for BMW 4 Series xDrive F32 F33 F36 - Pair

Give your F3x xDrive a sharper, more connected drive. This PFF5-4102 upgrade replaces the factory rubber mounts at the inner end of the front lower wishbone with high-performance polyurethane, delivering tighter steering feel, cleaner turn-in and greater braking stability on British roads.

Engineered by Powerflex and used by our team and customers, these front arm-to-body bushes are approximately 8 percent firmer than the standard items, reducing deflection under load so alignment stays true during cornering and hard stops. The result is more precise feedback, improved road holding and confidence whether you are commuting, enjoying B-roads or building a fast-road setup.

• Direct-fit replacement for the front lower wishbone inner mounts on BMW 4 Series xDrive F32, F33 and F36
• Polyurethane construction resists oil, heat and road salt and outlasts ageing rubber
• Reduces arm movement to keep geometry consistent for better grip and stability
• Helps cure vague steering, tramlining and uneven tyre wear associated with soft or worn bushes
• Excellent balance of performance and comfort with controlled NVH
• Lifetime warranty from Powerflex for long-term peace of mind
