I have used Factory Five 17X9's all the way around. They have a +24mm offset. You can use 245 x 45 R 17 fronts and 275 x40 R17's rear. This is with standard width 03-04 rear axle housing with standard width 03-04 axles There are other options but would require custom wheels, Richard Oben can help with those options.
