Transform the rear end of your 5 Series with this premium polyurethane rear top wishbone inner bushing set. By replacing tired factory rubber, these uprated inner pivot mounts keep rear geometry locked in under acceleration, braking and cornering, delivering crisper turn in, more stable high speed behaviour and noticeably better confidence on B roads and motorway runs. Ideal for drivers seeking a handling upgrade, suspension refresh or a durable performance bushing solution for fast road and track day use.

Why this upgrade makes a difference

• Sharper rear axle control with reduced unwanted camber and toe change
• More precise steering feel and improved braking stability
• Helps reduce uneven tyre wear by holding alignment true
• Polyurethane construction resists oil, salt and road grime for long service life
• Excellent balance of firmness and comfort with minimal NVH increase
• Backed by the Powerflex Lifetime Warranty for peace of mind
