For quite some time the right hand side backing plate is NLA and no sign of new production starting any time soon. With old stocks drying out, we were urged to come up with a plug and play solution.
On offer is a brand new pair of rear backing plates for E21 323i that can be used as a direct replacement. No modifications needed, 100% plug and play. Finished in long lasting semi-gloss powder coat instead of the normal flimsy factory coat.
