Definitely go the aftermarket rims. Stay away from the cheap crap you'll find at Bob Jane or other generic tyre shops. Also stay away from Tempe Tyres, heard lots of bad stories about those guys plus their rims are cheap crap! Don't skimp on width either, the XR is a big car so you'll easily be able to fit 10" wide rims on the back, not sure if you'll need to flare the gaurds or not... And one of the most important things to consider is OFFSET!! So many people don't have a clue about offset and buy cheapo rims with poor offset which then gives the povo Aussie spec sunken rim look. You want the rim to be inline with the gaurds or even sticking out a little (even though this is illegal, it looks TOUGH!)
