Polo 9N Wheel Size Questions

[VWindahouse]

Hi there, I was wondering how some of the tuning companies ie. BB's Garage are fitting 18x8" alloys and 215/35R18's on the little Polo? I think I have read in a thread on this forum that Guy from APR only uses 17x7.5" and 205/45R17 for street and when he races, reason being when he used 215/45's he had some pretty bad scrubbing.

Thanks for your help
