Laura, thanks for the reply.
Its re-assuring to know that the trim can be switched easily
I think the main reason why MINI left the ONE D bumpers alone was that the engine requires a larger front intake for the intercooler, as the diesel engine needs more air. But I dont think this would be a problem, because the S front bumper has a pretty large front intake, infact I'd say it was either the same size, or slightly larger.
I know of a ONE D with Cooper S bumpers, but the guy has an aftermarket twin exuast system on it, so the rear bumper has been heavily modified anyway.... which was why I wasnt sure if it was possible to simply replace the bumper trim.
So based on that I should think they would fit ok for me?
James.
