Umm you don't want Rotas but it looks like 3/4 of those pics are Rota Grids and Rota Torques?
Or are you referring to that stance crap?
Edit: Also two of those cars are wide body/ flared.
There's a fitment thread somewhere on these forums that explains it all but basically decide if you want to go 17 or 18 inch and then just choose width and offset.
I have 17x9 +48 on my car and they sit pretty flush, without requiring huge amounts of camber or stretched tyres.
