Best way to spend last 600 bucks

Your'e right I was thinking P225/60R14 or P235/60R14 BF Goodrich TA Radials for the rear which should give me about 24.5 inches in height which would have me crossing the line about 5800-6000. Not sure what I (safely)can get away with on the front, anyone know???.I may have to put the tires on the credit card and give them to myself for Christmas LOL. I think I can get them in there without having to hack or chisel????
