Flip kit questions

Just so you know..a flip kit for nbs drops 6" and shackles another 2" so you would be at 8" rear drop..

I will put the stock shackles back on it. Thank you for clarifying that though. I was trying to think if the shackles would make it a 8" drop or a 4" drop.
 
I'll do stock shackles and flip kit. Then it will be 6" from stock height, which should be 2" lower than the front.
