Yes, technically illegal - but I have the same on my car and have not yet been pulled over by the Police, so I say go for it. I think it might also be an MOT fail so keep a set of legal plates for MOT purposes.
Make sure you get the right size plate sticker as well. My first one was too large and creased on the curves of the front wings. It was replaced with a smaller one which looks much better.
Thanks David,
Please could you confirm the dimensions of your smaller plate so I get mine right first time?
Thanks, Dave.
