That happened because I used to go through the speedbumps really fast on my right side (after I lowered it) but not my left and it messed up the camber and alignment. Maybe I had bad installation but I had them installed at California Tint (They've been doing installations for years). After I got the results from taking it to the shop, both told me that my left rear is fine, only slightly off; however my right rear needs to be cambered so I don't think it was an attempt to cover their butt.
Well I guess if you drive it like a grandma over those speedbumps/driveways EVERYTIME and never will hit a curb, you wouldn't need a camber for a while. Because just one big bump, your camber and alignment will be off. I'm saying this through my experience, not out of my a$$.
Yeah and I basically did it for the looks and to get rid of the "floating on a boat" feeling on highways.
"Caving in"? Are you talking about increased negative camber on the car itself or irregular wear on the tire?
And speedbumps are meant to go over slowly haha, that's why they are there. And hitting curbs? I don't think most people do that on a regular basis.

Hitting curbs and or speedbumps at a high speed will mess up the alignment on any car, lowered or not. But the alteration will be most likely in toe in or out, not in camber. Camber is a function of ride height on our cars.
Does it look like I go fast over speedbumps and driveways?
