Been thinking about changing the wheels on my car. I have a B7 170TDI Avant. It has the BBS pattern alloys rather than the Ronals. They need a refurb and new tyres so I'm thinking about changing to 19"s - my mother has a B7 saloon with the Ronals but prefers the BBS so we will do a swap. Anyway, do RS4 19"s fit a B7? Are the reps good quality at all? I know its not very original but the other type of alloy I like are the BBS CH - or the BBS split rim style alloys. If I had the BBS style splits I'd like them staggered - would I need the arches rolling? - particularly on the rear? Any help really appreciated.
