Powerflex Rear Sway/Stabilizer/Anti-Roll Bar D-Bushes/Bushings 22.5mm for BMW E46 M3 (CSL) & Z4 M (E85/E86) - Poly/Polyurethane ARB Bracket/Mount Bushes PFR5-4609-22.5 (Pair) OEM 33552282682

Rear stabiliser bar D-bush set 22.5 mm for BMW E46 M3, M3 CSL and Z4M - Part number PFR5-4609-22.5

Give your BMW the crisp, planted feel it deserves. This high quality urethane bushing pair replaces the soft factory rubber at the rear roll bar brackets, tightening chassis control and unlocking sharper response on road and track. Designed for cars running a 22.5 mm rear bar, these bushes help your anti roll system work exactly as intended, improving turn in, mid corner balance and traction out of bends.

We run these bushes on our own builds and our customers love the transformation. Expect a tighter rear end, reduced body movement and more confidence when you push on. Fit once and forget with long term durability and a Lifetime Warranty from Powerflex.

Why this upgrade works

• Direct fit replacement with no permanent modifications required

Real world benefits

Whether you are preparing for fast road driving or your next track day, this bush kit restores precision to ageing cars and elevates handling on fresher examples. Reduced flex lets the rear bar do its job, cutting roll while maintaining composure and feedback. The result is a more connected M car that rewards commitment on B roads and inspires confidence at speed.
