Kinda depend on how much of the car you have and what you want to end up with. You can push the front axle out suicide style to get it lower, or Z the front like above. Keep in mind, if you leave the axle under the motor, no matter how low the body is, the motor has to clear the axle.
1" is too low for a frame unless you run bags. 3" is about as low as it is possible to drive without getting hung up on everything. 4" is pretty safe clearance. Also consider scrub line. If you have a flat at speed, you don't want the frame to dig in and flip you.
Take a look in the builds section. You'll be able to find examples of several different ways to lower.
