Lowering kits options

I'd like to lower my ride by 1" or maybe 1.5". I've seen options ranging from flipping the mounting brackets, lowering blocks or complete kits including springs.

I don't race the car so I'm not looking for the best option for traction. I just think my car would look better lowered a bit.

I know that I can lower the front by simply adjusting the torsion bars. But what do the experienced members here recommend for lowering the rear?

I really don't want to spend $500+ on the Hotchkis kit but if I will if it's my best option. I'm more inclined to go with lowering blocks.
