Powerflex PFR5-504-20 Rear Anti-Roll Bar Mounting Bushes 20mm (Pair) for BMW E46 3 Series inc Touring & M3 - Polyurethane ARB/Sway/Stabiliser Bar Bush - Replaces OE 33551096669

Powerflex Polyurethane Rear Bar Mount Bush Kit — 20 mm — PFR5-504-20 — BMW E46 inc Touring and M3

Dial in crisp, confidence-inspiring handling on your E46 with this Powerflex PFR5-504-20 rear bar mount bush kit. Swapping tired rubber for performance polyurethane tightens the back end, curbs unwanted movement and helps the tyres stay planted. Expect sharper turn in, steadier mid-corner balance and more predictable grip that lasts.

Designed as a direct replacement for the factory rubber mounts, these bushes control roll bar movement without the sponginess that creeps in as OEM components age. Powerflex’s material is engineered for durability and control, delivering long-term precision with road-friendly manners and a lifetime warranty.

Why enthusiasts choose this upgrade

• Noticeably tighter rear-end control for fast road and track day use
• Improved steering response and reduced body roll
• Consistent geometry under load for more stable cornering and braking
• Resistant to oil, salt and heat for year-round reliability
• OEM-plus feel with robust polyurethane construction
• Backed by Powerflex lifetime warranty
