Trying to make everything fit, need advice

My advice is to be patient and get your wheels and tires mounted and then mock everything up.
Do your measuring and then you will know exactly what you need for width when the rear diff is narrowed.
This will probably save you some headaches and potentially some money in the long run, and i bet there's lots more you can do with the car while you're waiting..........

So new update. I've found the ability to get the wheels sooner. much sooner. I just need to know what to do about the front wheels. My choice is either a 15x4 with 1.75" BS or a 15x7 with a 4" backspace. I was planning on going with the 15x4 but I'm a little concerned tha tthe car will be completely useless except for in a straight line. My concern with the 15x7 is that if the car sits low in the front, that the tires will rub the fender. Any insight on the 15x7 fitment would be great. Or just opinions on the front setup would be awesome.
