4 link rear with coil overs?

I started with the 200's at QA1 recommendation, I think its would have been fine with everything stock, but its not, I really don't know how a guy chooses what to start with, maybe if I had a scale that could weigh the weight on each tire?? Hell I don't know??
Im QA1 uppers and lowers up front with PST 1.03 bars
