Get your BMW turning in tighter and exiting flatter with this uprated rear bar mount set from Powerflex.

Part number PFR5-4609-18. OEM cross-reference 33552283073.

We run these on our own cars and customer feedback has been excellent for road holding, confidence and overall balance. If your E60, E61, E63 or E64 feels loose or wanders over bumps, fresh poly rear bar mounts are a proven, high-value fix that transforms the way the car tracks and grips.
