Bobby,
Sound like you have similar pieces to mine. I run my Strange adjustable RR shock much stiffer than the rest to help the squat, I usually am at 30-35 in the RR bag. Same set up in my SSer. No magic and it launches pretty evenly now. I do use factory sway bar and 27.5 front runners. If I run a lot of weight in my P/SA I go back to stock rear springs with no problem.
