I have recently put on 20" adv with aggressive offset and install BC coilover at the same time. For some reason, rear left wheels pokes out more than the rear right, may be 2-3mm more if I have to guess. Is this strictly alignment issue or I have mismatched offset? Thanks.

Check whether they both have the same offsets, first. Then if the wheels have the same offsets then perhaps camber alignment issue. I had a similar case on a different car a few months back and it turned out that the camber on the front passenger side is off..

This is the left side, passanger side in Indonesia


This is the right side (driver) with 3/4 tank.

I'm located in Jakarta too Anyway, looks like you've got a wrong offset from the pics..

Really? I will swap the rear wheels and see what happens. My tyre is outside/inside type, shouldn't be a problem i guess.

Looks like it. At least to me. Try this, unmounts the wheel in question, look at the back of the wheel, you should see a writing "ET", and compare it to the other side

I highly doubt the wheels have different offsets then each other. Being that you're on coils make sure they are evenly lowered.
I know from experience that the right rear sits lower then the left which will make the wheel camber in more.

Tip, You might want to lower your rear right a bit more or raise your rear left a bit to compensate.

Did you mean raise the rear right or lower the rear left? Since the rear left is the one that is poking out. I will try to measure the height on each corner to make sure that the rear left needs more drop.

What LACSTER meant to say is that try lowering the side which your wheel is poking out

As I was told by BMW representative, that is normal (rear axle off center), I have oem mpeformace wheels on my f11 (self leveling air suspension on the rear axle) and my rear right wheel is tucked in 3mm more than left one, same as in your case.

I just got an alignment to run more camber on the back, around -2.20 and that side is still rubbing. Do you guys think running stretched tires would resolve the problem? I'm afraid that the wheels poke too much where the lip would hit the fender anyway (with stretched tires) if I ran into big dip on high speed. The highway pavement in Indonesia is really bumpy.
