Advice asked for widthening rims on a 70 Duster

George Jets, yeah, I was thinking that too. To solve the problem of the car being too high in the front I was thinking to go to 205/70 instead of the 75 currently. That way the stance will be better I assume, when 235/60/14 are mounted in the back.
There would be only a difference in height less than a fifth of an inch I calculated. Speedometer would only be 0.78 % off
