Transform rear end stability and steering feel with this Powerflex polyurethane upgrade. By replacing soft, ageing OE rubber at the outer joint of the rear upper arm, these performance bushes limit unwanted deflection, helping your E9x hold toe and camber more consistently under acceleration, braking and cornering. Expect crisper turn in, better traction out of bends and a more planted, confidence inspiring drive on fast road or spirited B-road use.

Why enthusiasts choose PFR5-412

• Improves chassis precision and rear axle control for a more connected driving experience
• Helps maintain alignment under load to reduce rear steer and mid-corner movement
• Supports even tyre wear by stabilising toe and camber settings
• Durable polyurethane resists oil, salt and heat for long service life
• Designed for performance without harshness for excellent NVH balance
• Supported by the Powerflex Lifetime Warranty

We fit these bushes on our own projects and customer cars and the difference is immediate. Customers report tighter rear axle behaviour, improved braking stability and more consistent grip in wet and dry conditions. It is a simple, effective upgrade that pairs perfectly with quality tyres and a proper alignment.
