Powerflex Black Series Rear Spring Levelling Spacer for BMW 1 Series and 3 Series - PFR5-427BLK

Sort out the classic right hand drive lean and sharpen chassis response with this competition-grade rear spring seat spacer. Built from ultra-stiff 95 Shore polyurethane, the Powerflex Black Series insert replaces the thin OE pad to even out rear ride height, improve stability and deliver a tough, long lasting solution that resists wear, oil and road grime. Simple to install, transformative on the road and track, and proven on our own builds as well as customer cars.

Why it is a must-have upgrade

  • Levels the rear on RHD cars, correcting the common driver side sag for a straight, confident stance
  • Stiffer spring interface for cleaner suspension geometry and crisper turn in under load
  • Black Series compound, engineered for track, race and rally with outstanding durability
  • Direct swap for the factory spring seat pad for a clean and reliable install
  • Flexible setup, fit one spacer to correct lean or fit a pair to raise both sides of the rear axle

How it alters height

Replaces the approximately 5.7 mm OE rear spring pad with an 11.4 mm spacer. Net change is about +5.7 mm where fitted.
