Jacking a car from one side is actually really hard on them. Especially lowered ones that have quite a bit less wheel travel.
I have a craftsman floor jack that i use on the front in the center. On the bottom of the radiator support is 2 large bolts that hold the front engine/tranny support on. The jack will "cup" the bolt, it wont slip off, and its a very strong place.
In the back, do it from the center of your suspension, where the lateral arms meet in the center. If you make a shorter handle for your jack, about 9" long you can jack up the car for a ways first, then use your normal handle.
Ive had lowered cars for almost 15yrs now, and have always done them this way, never had a problem.
