BMW E46 & Z4 E85/E86 rear subframe bush insert PFR5-4613BLK

Powerflex Black Series PFR5-4613BLK inserts fit the rear subframe bushes on BMW E46 (all body styles, M3, CSL, Xi, XD) and Z4 E85/E86. Not for E89 or Z4M - those require different parts.

Made from 95A polyurethane, they reduce deflection and stabilise rear axle geometry under load - useful for fast road use or track days where precision matters. NVH stays manageable; no jarring harshness on UK roads.

• Fits OEM bush housings - direct replacement, no modification
