Powerflex PFR5-427 Rear Height Corrector for BMW

Cure the classic right-hand-drive lean and even out the rear arch gap with the Powerflex PFR5-427. This precision rear coil spring pad lifts the low side to give your BMW a level stance, cleaner tracking and more consistent tyre wear. Built in Powerflex Road Series polyurethane for long-term durability, this is the simple fit-and-forget solution enthusiasts choose for everyday road use and spirited driving.

Key gains

  • Levels UK right-hand-drive cars by replacing the thin factory pad with a taller 11.4 mm spring seat
  • Sharper steering feel and calmer rear end over bumps and loading
  • Improved contact patch and reduced shoulder scrubbing
  • Resistant to oil, road salt and debris for a long service life
  • Can be fitted on both sides if you want a subtle rear lift

Why enthusiasts buy this part

We have installed PFR5-427 on our own cars and many customer vehicles. The feedback is always the same - immediate visual improvement, straighter tracking and a more planted feel without harshness. It is an easy, cost-effective fix for the annoying driver-side drop on many UK BMWs.
