SC lowering and alignment
Since the Supra suspension parts lower the SC an additional 0.5", most of the mild lowering springs even 1.5" translate to 2.0" on the SC..
At what point does the alignment gets out of whack and require a camber kit?
I am asking because I don't want to have too much effect on chewing up the tires. But a negative camber of around 1 degree might be a compromise between tire wear and handling.
extra question: if I lower the SC height around 1.75", do I have to do anything about rubbing or relocate the wire harness, I think that is very conservative the early SC seems to have a 4" fender to wheel gap so 1.75" should not get to rubbing at all.

I relocated my d side wiring with a 2 inch drop, it's done there, but the metal tab is still cuts into the tire 
I think anything more than 2 inches would definitely require some kind of camber kit.
Without an alignment inner side of my tires are gone bad gone

The acceptable camber range for the SC is -.7 to .8, in the front, so -1 isn't that far off from stock spec.
It's hard to say at what point the car requires a camber kit because it is all personal preference. I'm not sure how much my car is lowered since I'm on coils. I just installed them at a random height that looked good to me. My car has -2.4 degrees of camber in the front and it handles fine. My tires are not rated to last that long to begin with, so the tire wear doesn't seem too bad to me.
I would relocate the harness as a preventive measure. It is so easy to do that there is no reason you should skip the step. Fixing a damaged is a lot harder than relocating the stock one.

if you ever mess with suspension its always good to get it checked, visually check your wheels if you have any toe, and camber, I know for sure i need one right now, and my xb needed one when i threw on the coilovers. also if your car pulls you need an alignment. My car gets shaky at times going over bumps most likely due to how much natural camber i got when i lowered mine, noticed my car started pulling to the right a few days ago so ill be checking my control arms to see if they're bent or if worst comes to worst i need my frame straightened.
