The subtle difference between this and any other Cooper grille is the second slat, it has no opening for the bonnet release lever. This gives a very clean look only to Minis fitted with an inside hood release. The fins on the stainless steel although much stronger are slightly prouder so BEWARE if you have Rover spots fitted as per some late Coopers, there might not be enough clearance.
The wide slats are made in autumotive type 430 stainless steel which means any stains created where it would attach to ordinary metal can be polished out.
