I like the look with aero blades. Agree it’s really hard to see the caliper without them. Plus, 99% of people will have no idea what the caliper is or what it means. From a pure look perspective, totally subjective but the lugs are ugly AF (as my kids would say), so you need to cover those if you remove the aero blades.
My de came with center caps and lug nut covers in a bag with screws for the front license plate holder. Not sure if that’s normal.
