Stupid question? Can I replace my torsionbars and leafsprings for coilovers?

Also ESPO will make lowering springs.

No one has mentioned front leaf spring hangers with a higher bolt hole location. You can buy or make them. A 1" higher hole will lower the car 2" at the bumper.
I think you might have that backwards. If you’re moving just the front mount up 1 inch, I think that’s only going to lower the car 1/2”
Someone correct me if I’m wrong
