Why choose polyurethane here

Ageing rubber can allow excess movement that dulls steering response and causes geometry creep. Powerflex polyurethane controls arm movement far more consistently than standard rubber, keeping your X3 composed over bumps and during hard cornering. NVH is kept in check thanks to clever material formulation, giving a performance feel without sacrificing everyday refinement.

Adjustment option

Need camber adjustment as well as new bushes? Choose PFR5-4615G, which provides on-car adjustability. Select PFR5-4616 when you want a high quality OE-style press-in bush for the original arm at the inner mount.

Tried and recommended
