Regarding the radio reception, i don't really listen to it much. This was my main reason for changing to the stubby, aesthetics more than anything.
The badges - they've been on a couple of months now, and no sign of them peeling off. You actually have to look hard to tell that it's vinyl stuck over the original colour... unless you've got a wonky hand when putting them on. It's my daily drive, so we'll see how they fair over the winter months, especially on the wheels.
I wasn't too sure when i first ordered the badge vinyl, thought it could look amateurish, but for only a few quid i gave it a go. Got to say, it does do the job quite nicely if you fancy a non-permanent change.
