There is no "correct way" to raise your back end.
Because raising the back end is never optimal in a car.
It shifts the weight forward, lessening traction and braking.
It raises the CG, making handling worse.
When I see a car with it's rear jacked up it tells me musclecar equivalent of a ricer.
Don't care, cars like mine look terrible at stock rear ride height. Like an old granny with a dragging ass.
It was done 20 years ago so I couldn't tell you. A 28" tire fully clears the rear wheel well lip in terms of height.
