Upgrade the rear-end precision of your BMW 1 Series F20 and F21 with Powerflex Black Series Rear Subframe Front Bush Inserts. Designed for track and motorsport use, these performance polyurethane inserts fit into the voids of the original OE bush to reduce subframe movement for sharper handling, improved stability and maximum control of chassis geometry. A proven suspension bushing upgrade for enthusiasts who demand consistent performance on circuit and aggressive driving.
