As Benny Said it really does come down to offset as well as the spokes for the rims.. you just have to go and literally have the tried on before you buy at the end of the day. typically Australian made (except for ROH and Simmons which you can get custom offset, 3 piece wheels made to order) and Taiwanese wheels have limited offsets available for each stud pattern. So if they style you like doesn't fit you brakes you have buckles chance in them having a different offset typically. As other have said you will have a lot more luck in looking into Japanese wheels (WORK, VOLK RACING, RACING HART, WEDS, RAYS etc) as they typically make heaps of different offsets for the falcon PCD which is the as Nissan and other popular RWD Jap cars that run wider wheels/different offsets on the front and rear. The problem you will encounter there though is most "Tuner" wheels are no bigger than 19 inches, Also do not expect to get much change out of 1k AUD (due to how our dollar is performing) per rim. sorry I couldn't of been of more help mark.
