Rear stabiliser bar bushing set 18.5 mm for BMW X3 E83 2003-2010 - Powerflex PFR5-4609-18.5
Give your BMW X3 E83 sharper road manners with this high-performance rear stabiliser bar bushing set.

Ideal as a long-life replacement or as a handling upgrade for daily use and spirited driving.
We run these on our own builds and for customer cars, and the feedback is consistent: tighter turn-in, better mid-corner stability, and more predictable grip without adding harshness. A simple change that makes your X3 feel planted and precise.
