Polyurethane Rear Cradle Insert Bush Upgrade for BMW F Series 1 2 3 4

Unlock tighter rear end control, improved traction and a more planted feel with this Powerflex polyurethane rear cradle insert bush. Designed to locate in the voids of the factory rear carrier mounts, this insert limits unwanted subframe movement for sharper response on fast road driving and daily use, without the expense of a full bush replacement.

Price is per insert. Two inserts required per car.
