Poly Bush Kit - Front Stabiliser Bar 21.5 mm - BMW E46 AWD 4x4 - PFF5-4602-21

Transform the front-end feel of your BMW E46 all-wheel-drive with this Powerflex polyurethane front stabiliser bar mount kit, part number PFF5-4602-21. By replacing tired factory rubber with high-grade poly, these mounts cut unwanted bar movement, tighten steering response and keep the chassis composed, helping your tyres maintain consistent contact for confident road holding.

Ideal for daily driving and spirited B-road use, this pair of 21.5 mm front roll bar mounts delivers a cost-effective suspension upgrade that you can feel from the first drive. We have fitted this exact kit on customer cars and our own vehicles with excellent results. Feedback is consistently positive for sharper turn-in, improved mid-corner stability and a more connected front axle.
