Powerflex Poly Bushes Pack - Rear Roll Bar Mounting Bush 20 mm - PFR5-504-20 - BMW E46 3 Series inc Touring
Transform the handling of your BMW E46 3 Series, including Touring, with Powerflex polyurethane rear anti roll bar bushes. This PFR5-504-20 20 mm rear roll bar mounting bush kit tightens up the rear end, reduces unwanted chassis flex and keeps your tyres in better contact with the road. Expect sharper turn in, improved stability and more consistent cornering performance from a simple, durable upgrade that outlasts rubber.
These performance poly bushes directly replace soft, ageing OEM rubber bushes that cause imprecise handling, uneven tyre wear and braking instability. Powerflex correctly formulated polyurethane controls movement without the excessive noise, vibration and harshness you get from worn rubber, giving you an OEM-plus feel with long term reliability and a lifetime warranty.
