Hey, i just bought wheels for my silver vy ex, i got advanti viennas 19inch for 500 brand new of a family friend, they were cheap so got em, not sure if they suit the car that much yet, ill wait till i put em on ay, i think they will, havnt put em on yet cas pay hasnt come through n dont get my p's until 2 weeks, im pritty much doin the same mods that u listed aswell.
Id definately go the first wheels listed, a mate of mine has 20 inch ones on his vy ss and they look sik, they suit vy's so much.
also have a look at these rims called rjr tremors 'chrome ones' in bob janes range
i was keen on buying them for my car before i got the advanti offer
goodluck with ur choice
