Powerflex Polyurethane Rear Anti-Roll Bar (ARB) Mounting Bushes 22.5mm for BMW E46 3 Series incl Touring PFR5-504-22.5, Pair

Uprated Rear Stabiliser Bar Mount Bush Kit 22.5 mm for BMW E46 3 Series inc Touring | Powerflex PFR5-504-22.5

Transform the back end of your E46 with this genuine Powerflex polyurethane mount set. By replacing tired factory rubber on the rear sway bar, these bushes lock the bar in place, cut unwanted movement and deliver sharper steering feel, reduced roll and rock-solid stability. Ideal for fast road, B-road blasts and track days where consistent chassis behaviour matters.

• Significantly tighter bar location for cleaner turn-in and predictable cornering
• Keeps suspension geometry consistent under load for improved braking confidence
• Durable polyurethane resists oil, salt and heat for long-term performance
• Can reduce tyre scrub and help extend tyre life compared with worn OEM rubber
• Excellent value upgrade with a Powerflex lifetime warranty
