So..... I got the wheels fitted today and also had the shadowline trim replaced at the dealers - so as far as car days go - this was a good one!
Over the moon with the wheels, and the tyres look awesome too with the silver P Zero logo. Also swapped over my centre caps to make the whole set up look OEM.
I went with the more conservative 225/35 and 255/30 set up just to avoid any rubbing, and they have done the job. No hint of rubbing at all so far, so very happy with that. The trade off is a little more stretch, but to my eye they look perfect.
