Rear Stabiliser Bar Bush Kit 13.5 mm for BMW 5 Series E60 E61 and 6 Series E63 E64

Unlock confident cornering and a planted rear axle with this premium polyurethane rear stabiliser bar bushing set. Engineered to replace tired factory rubber mounts, these performance poly bushes deliver tighter roll control, crisper steering feel and dependable road holding on your 2003-2010 BMW 5 Series E60 E61 and 6 Series E63 E64.

Built for daily driving and spirited B-road use, the uprated material resists deflection, heat, salt and oil, helping to reduce unwanted movement in the suspension and keeping the rear of the car composed under load. Expect cleaner turn in, improved stability mid-corner and more consistent behaviour over rough surfaces.

• Polyurethane rear bar mounts for sharper response and reduced roll
