PFF5K-4601 Front Wishbone Rear Bush & Bracket fits BMW E46 and Z4, excluding M3, and uses our PFF5-4601 bush, covering both 60 and 66mm size options. No more guessing or measuring required! A lasting, better-performing polyurethane bush alternative, like Powerflex, has always been a popular upgrade for owners but whilst our bushes are very easy to fit, sometimes removing the original bushes from the OE housing brackets can be difficult, especially for those with limited access to pressing or pulling tools. Pre-installed in quality supplied brackets, they simply require fitting onto the arm and bolting into position saving both time and money.
