Tire and Rim question?

[69charger440]

I am trying to get 315 or 325 /40/18's under my 69 charger!! I will be making a dana 60 for these tires. I will also be using the Lynx rear suspension from Reily Motorsports. Will these wheels and tires fit with out rubbing on a unmodified wheel tub in the rears!!!???

I think a 315 or 325 is most likely going to rub without modifications. I run 285/40/18 rears and its got a little room for a bigger tire but not too much. I know a 295 should fit and with the street lynx setup a 305 might fit? 315 maybe with the right offset and trimming or rolling the wheel opening?

Here is a guide to help mess with offsets that I used when I was getting my wheels. Its not totally accurate but it helps give you an idea of whats possible.
