Is this car still floating about?!
Did you get any alloys in the end Ollie?
I like them. Parada Spec 2s are however, utterly garbage - try something else.
205s might look a bit stretched on a 7.5 - maybe a 215 or 225?? Some of the Mini forums are probably more help for that, as the aspect ratio will have to be altered if you go much wider.
