Shaking under right turn acceleration only

So i did my research and couldn't find a whole lot...

Under right turn acceleration, and only under right turn ACCELERATION, my car shakes on the driver side severely, and sounds like either something is rubbing, or there's a weird fuel cut out happening. The only idea that i have is the brakes, but why would it shake when i'm making a right turn, or the steering wheel is turned right, and ONLY when I apply gas? If anyone has had the same issue please pitch in, or throw ideas at me. Going to put the car on the lift this weekend to try and figure out this ghost...

Are you getting engine lights or codes? It's possible the engine is hitting the subframe? How fast a turn causes this issue? I took a hard fast turn and pulleys hit the front subframe. Belt got shredded and due to some major damage, BMW replace my engine block! There is a TSB on the subframe issue.

Could be a warped rotor.

I dont think it's my pulley hitting the sub frame, or at least i hope its not...

Any more ideas as to what it could be?

Is that an educated guess?

It could be possible that your DP rotated & is now rubbing against the subframe. I say this because I had the EXACT same problem (except it was whenever I turned left). I see you have the CP-E DPs, which don't have the subframe mount, which is another reason why I also suggested this being the problem.

Very possible, I remember experiencing this odd vibration on during turns. If I recall correctly it was only left turns too, but I guess right turns are possible also.

Check your motor mounts. The aluminum bolts into the block often break.

After going thru everything on the car, its the lower control arm bushings, just in case anybody else has same issue, check that first...
