Any advice on lowering 1972 240z?

I have a 72 240z and I really want it to look nice and low. I know that Ground Control Coilovers work real nice, but they aren't in my budget. What are any alternatives to making my car as low as possible? What lowering springs/kit would look best and would getting smaller rims/wheels and tire profile reduce the ride height as well? I will be putting on ZG fender flares on and I want the wheels to look tucked in. I also plan on getting Konig Rewinds. So what do you think would make them look best on my car?
