Okay, 89 lx w/ all stock setup. Have 2" drop springs, but not installed...may not install. Looking at 17x9 cobra r's on ebay w/ 20mm offset. Want to go with 245/45 or 40 front and 235/45 or 40 on rear from tire rack. Is this the proper offset and what would this look like as far fender fill and tire extension outside the well? Recomendations as to 40's or 45's on front or back? Willing to remove quads if needed. What would happen w/ the 2" drop? Thanks
