Powerflex Black Series rear upper wishbone inner bushes are the ultimate suspension upgrade for BMW track, race and hard-driven road cars. Manufactured in a motorsport-grade 95 Shore A polyurethane compound, these performance poly bushes dramatically reduce arm deflection to keep alignment stable under load, sharpen turn-in, improve rear-end grip and deliver precise chassis control. If you are searching for BMW E46 rear upper wishbone bush, BMW Z4 E85 E86 E89 rear upper control arm inner bush, BMW M3 rear camber arm bush, or Powerflex Black Series bushes, this PFR5-4617BLK kit is the proven solution for serious performance and durability.
