Having done quite a few cars the thing I crave the most and want now is a nice unmolested stock 6 cyl dart like yours and I would Leave it as is. Simple, stylish, and rare! Almost all of them have been hot rodded ip and big blocked this and road coursed that etc….. it would be cool and nice to have a stocker! That’s my vote
Correct, I want it to handle/brake more like a modern car.
I have noticed that no one has mentioned mini-tub/spring relocation for wider tires. I assume moving the leaves inward adversely affects road handling?
So far, I'm getting some pretty good info that isn't contradicting in the same manor as some of the other suspension threads, so thanks everyone for the great replies! I really appreciate it.
