With only the back end raised, that's called the "raked" look. Old muscle car style. 😎
The alignment on these suspensions are complex, and not really logical - so any modifications will make for some unstable driving.
When you lifted the car, and the suspension drops, the bottom of the wheels move in (positive camber). Then when you drop the car back down, that wheel position likes to stay that way until you drive and loosen thing up again.
If you were to raise the suspension, say with a strut spacer, the positive camber would be your problem - an alignment would fix that, but you'll also need special parts to adjust the camber, as the Caliber's parts are [mostly] non-adjustable. The other issue I'm having is I've not found an alignment company that want's to mess with this car's modified lift (2", front & back) - every one says they only align "stock" cars... so there's that.
Lifting the rear will also change the way the front alignment handles, too. Things get wobbly and bump-steer becomes a noticeable issue which is a bit more complicated to fix.
Lifting any part of the suspension starts putting the CV axles at more of an angle, speeding up the chance for failure.
But, once you understand all that, and are prepared for replacing parts a lot more frequently, I think the custom look is worth the effort.
