15mm Rear Stabiliser Bar Bush Kit for BMW E8x, E9x and E84 X1 | Black Series | PFR5-4609-15BLK

Sharpen your BMW’s rear-end response with these 15mm rear stabiliser bar mounts from the Black Series range. Engineered from ultra-stiff 95A polyurethane, this upgrade replaces ageing rubber bar mounts to give crisper steering feedback, tighter body control and repeatable geometry under load. Ideal for fast-road, track day and competition builds, as well as daily-driven cars that demand precise handling and durability.

We run these on our own cars and customer projects. The feedback is the same every time: more confidence mid-corner, cleaner turn-in and a planted rear axle without added NVH from solid metal components. If your factory rubber has softened, split or is allowing the bar to move, this is the fix that lasts.

Key advantages

  • 95A hardness polyurethane for maximum control and minimal bushing deflection
  • Reduces roll and keeps rear alignment steady during hard cornering and braking
  • Consistent performance in heat, cold, oil and road grime compared with rubber
  • Direct-fit replacement on the correct bar size for quick installation
  • Long service life and repeatable performance for fast-road and track use

Specification

  • Bar diameter: 15mm. Please measure your rear bar to confirm size before purchase
  • Compound: 95A polyurethane
  • Pack contents: 2 rear stabiliser bar bushes
  • Part number: PFR5-4609-15BLK
  • Replaces BMW OE reference: 33556761360

Vehicle compatibility

Suitable for BMW models using a 15mm rear stabiliser bar:

  • 1 Series E81, E82, E87, E88 2004 to 2013
  • 3 Series E90, E91, E92, E93 including xDrive 2005 to 2013
  • X1 E84 2010 to 2015

  • Improved stability on B-roads and motorways with reduced rear-end float
  • Cleaner rotation and more predictable balance on track days
  • Perfect supporting mod for performance springs, dampers and wider tyres
  • Helps maintain rear toe and camber control under load
