I found that going from the original wheels to car tires greatly improved the tracking and ride. Lowering the CG while mathematically decreases lean..improvement in handling will be most noticed by front to rear weight distribution and leveling the stance.
I like the look of a 2 inch rake and lowering the front was a preference
I also have 3/4 ton leaf springs yet in the back so there is not much sway. I guess you could add some helper leaf springs in the back and even in the front to stiffen your 1/2 ton spring rate
