Weird. The passenger rear is actually lower than all the other corners for me.
Just to add to the Swift height database, this is after almost 9K miles:
26.55" driver side front
26.50" passenger side front
26.60" driver side rear
26.35" passenger side rear
For anyone about to install or thinking about installing springs:
Remember to torque down all the pivot point bolts with the suspension under load!
On the front, use a hydraulic jack under the brake disc to raise it up to where it would be while driving, then tighten bolts. The distance between fender and center of wheel bearing is about 14" under normal load with these springs fyi.
I wish I did this the first time around
