I have always liked the look of the big bum (sorry wide bodied Carrera S) with the 19"x11" wheels. I have a Cayman S with the Carrera Sport 19"x10" rear alloys. It currently has the standard fit 265 section tyres. Does anyone know if you can fit a 295 section Porsche approved tyre at the rear on the Cayman without any handling or space issues with the bodywork and/or rear suspension. Has anyone tried this?
