You may as well come to the terms that any stock spring will not add lift nor will it give you any decent articulation for good off road behavior. People who run chevy springs or trail-gear springs like what I have need to cut the stock spring hangars and shackle mounts off and weld new ones on. The longer springs are what gives the good flex.

I would suggest staying away from the zuk mod all together. It's a hack mod and implies redneck engineering at best.

If you want stock height, get new stock springs. They will last a long time before they start to sag again and won't bee too hard on the bank. If you want lift and flex then get longer springs (chevies or TG), you'll have to do some fab work and it will be more expensive.

Unfortunately, you cannot have a good articulating suspension in stock form. It's a trade off.
