Audi Allroad alloy wheels advice

[JRAMOV6]

Hi there was wondering if enyone could help me out with wheels n tyre sizes that are best for an allroad c5 2004 i preferably want the rs6 5 spoke wheels or the 9 spoke 1s and was wondering will they fit straight on the car without spacers or will spacers be needed due to the wheel arch size on the allroad my car also has bilsteins fitted allround will this make eny difference to bigger wheel fitment .Eny advice is appreciated or enyone who has owned a allroad and has bigger wheels fitted would like to hear your set up .Cheers
