SuperPro Polyurethane Suspension Bush Kit (Full Car Set) for BMW 3 Series F30 F31 F34 F35 & F80 M3 | Poly Bushings Upgrade: Control Arm, Wishbone, Trailing Arm, Subframe, Anti-Roll Bar

Polyurethane Suspension Bush Kit for BMW 3 Series F30, F31, F34, F35 and F80 M3

Transform the way your BMW rides and handles with a complete polyurethane suspension bush upgrade. This comprehensive kit replaces tired factory rubber with high-grade performance bushes designed for sharper turn-in, better stability under braking, reduced flex and more consistent alignment on road or track. Ideal for fast-road builds, daily drivers that demand precision and F80 M3 owners wanting maximum chassis control without harshness.

Engineered to control unwanted movement across key front and rear suspension points, these performance bushes help keep your wheels aligned under load, improving traction, grip and steering feel while reducing uneven tyre wear. The material is resistant to oil, road grime and heat, offering long service life with minimal increase in NVH thanks to intelligent shaping and durometer selection.

Why upgrade to polyurethane bushes

• Crisper steering response and improved cornering stability
• More consistent geometry for better traction and braking
• Reduced deflection compared with ageing rubber components
• Durable, wear-resistant compound for long-term reliability
• Helps reduce tramlining and keeps tyres square to the road
