well I went and dun it.....i cant remember the backspacing on the wheels off hand but .. the rears are 18x9.5.. fronts are 18x8 ..i used a jegs 2 inch drop spindle with a 1 inch drop hotchkiss coil up front and a 3 inch drop coil out back.. the tires rub slightly on the rear frame so i bumped it out slightly with a 1/4 inch spacer. all it needs.. the tires tuck nicely..nitto nt555 tires... 235/40 up front and 275/75 in rear..
