Uprated Rear Crossmember Mounts for BMW Z3 1994-2002 - Powerflex PFR5-311

Give your Z3 a serious chassis refresh with this pair of Powerflex rear crossmember bushes. Replacing tired OE rubber with high quality performance poly bushes tightens the back end, stabilises the rear subframe and restores crisp, predictable handling on road, fast road and track day use. If you are feeling rear end float, tramlining or vague steering, this rear beam mount kit is the proven fix.

Uprated poly bushes control deflection better than ageing rubber, keeping alignment true under load. With the rear subframe properly located, the suspension can do its job, maximising grip and driver feedback while maintaining everyday drivability. This is a cost effective, fit-and-forget chassis upgrade for any Z3 enthusiast.
