We have reproduced the obsolete JCW Aero Grilles, bringing you grilles that look like, and fit like the real thing!
The upper grill is made to fit any bonnet, including the R50, R52 and R53.
The lower grill is made to fit the JCW Aero kit, however many people do fit them to the S and One / Cooper bumper with slight modifications - see here. In a nutshell, the S bumper has a shallower recess for the lower grill, and clips in a different place. The depth of the Aero grill needs to be trimmed to fit the depth of the S bumper, so it fits flush with the bumper, and bonded in place.
