Powerflex Black Series Rear Anti Roll Bar Bush 11mm for BMW 1 Series E81 E82 E87 E88 & 3 Series E90 E91 E92 E93 (E9x/xDrive) Polyurethane - PFR5-4609-11BLK - OE 33536765584

Rear Sway Bar Bushes 11 mm – BMW E81 E82 E87 E88 E90 E91 E92 E93 – Powerflex Black Series

Transform the rear-end feel of your BMW with these 11 mm Powerflex Black Series stabiliser bar mounts. Using a motorsport-grade 95 Shore A polyurethane blend, these uprated poly bushes minimise flex at the rear axle for crisper turn-in, flatter cornering and a more planted, confidence-inspiring drive on fast road, track days and timed events.

We run these on our own MJ Modifications builds and the feedback is consistent – tighter rear-end control, better mid-corner stability and a more direct connection to the chassis compared with tired rubber mounts. If you want repeatable handling and long-lasting performance, this is the go-to rear bar bushing upgrade.

Why this upgrade works

• Stiff 95A polyurethane helps maintain rear geometry under load for predictable handling
• Sharper steering response with reduced body movement through quick direction changes
• Highly durable vs OE rubber for hard-driven road cars and competition use
• Consistent performance in heat, cold and under aggressive driving
• Direct replacement for the factory rear stabiliser bar mounts
