Hello all, I have a 2012 R55 JCW clubman with the JCW side skirts that do not have the rear vents. I am now trying to add on some JCW Aero side skirts with the vents but the thickness of the bottom are differerent. My original ones are about 7.5 inches wide while the Aero ones are about 4 inches wide. The clip holes do not line up. Is there a difference in Aero side skirts for pre LCI vs LCI? Any help would be much appreciated.
