I believe he meant if you drop the car all the way around you will improve handling
I meant if you drop the front 2" and leave the rear stock it will not improve anything to include looks. Springs are sold as set of 4 for a reason. You are trying to use aftermarket springs with different spring rates at different drop rate in unison with oem springs.
A 2" drop may require cam bolts, hard to say until you get an alignment, unless someone in here speaks from experience on the effects of 2" drop on an altima. I know a 2" drop puts my front camber out of spec, enough to need camber arms though, we will see based on tire wear.
I haven't figured out what 20" wheels have to do with alignment unless they are the wrong widths and offset.
