I know that was me being an idiot, I'm thinking while running the standard diff and 5k maybe 8's would be max on the rear. I was planning the flare the guards quite considerably, and as far as legality was concerned it wasn't coming into consideration, my pipes hanging 20cm our the rear of the car stand out more at the moment. As far as stretch goes most i would realistically run is 195 on an 8" rim so not overly noticeable and not completely nuts.
Although benzo has got me into not cutting up the guards now, maybe a set of 13x7 all round would look better. I'm thinking the rear would still have to be pumped a little but nothing too dramatic. Also its more realistic considering my drive train at the moment, and they still look hot, nick super lights have a fair chunk of dish thats for sure.
