I just found RX8 in stock at a local dealer that is titanium gray with black interior which would be perfect but it also has the Aero package and the rear spoiler. I wouldn't mind the spoiler but don't think I want the aero

Does anyone know how the aero is attached and what holes would be left if I removed them ?

Are their parts I could buy to replace the parts with holes ?

there are four holes in the body about 10mm in size on the front side aero flares, the rear have a 1 inch slit and 2 holes cut into rear bumper cover and the front is no big deal if you have the original bottom piece which yours wont since it has the aero kit on it.
